Symbol Explanation

This symbol represents the

OPERATIONAL DISPLAY.

This is the PROGRAM button.

This is the UP button.

This is the DOWN button.

When a button is shown, press and

release it to go onto the next step in the

direction indicated by the arrow. When two

or more buttons are shown, each with an

arrow, this indicates that there is a number

of programming choices.

When two buttons are shown side by side

and enclosed by a dotted line, they must

be pressed at the same time then released

to go onto the next programming step.

If the display is shown with XXXX it means

the value displayed will be the previously set

value. When a number is shown it indicates

the initial factory default setting or a specific

“example number”.

When two displays are shown together with

bursts, this indicates that the display is

toggling (flashing) between the name of the

function and the value.

Text or numbers shown between square

brackets in a procedure indicate the pro-

gramming code name of the function or the

value displayed on the meter display.

When the

and

buttons are shown

together, the display value can be increased

by pressing and releasing the

button

or decreased by pressing and releasing the

button.

When the

and

buttons are shown

with two displays, either display can be

selected by pressing and releasing the

buttons.

When there are more than two display selec-

tions they are shown in brackets below the

first display and are also selectable by press-

ing and releasing the

buttons.

A dotted box indicates these functions are

omitted or bypassed when the related hard-

ware is not present

Texmate’s Modbus RTU RS-485 module provides

half-duplex, serial communication to PLC, SCADA and

other systems for monitoring and control of the meter’s

functions. The meter functions as a slave.

The RS485 module takes the place of the Analog Output

module, so it is not possible to have both Analog

Output and RS-485 communication. Programming and

operation of the meter are done via a dierent menu

system, or Software Logic Tree, that is accessed through

the front panel push buttons, see below.

When the rear Auto/Manual switch is in the Manual position, the meter can be rescaled without applying an external signal by

changing the oFSt (offset) and SCAL (scale) parameters in the user menu. A pre-calibrated Input Signal Conditioning module must

be used. The meter assumes that this calibration used a true zero input (0V from conditioner to meter) resulting in a display value

of 0 and a maximum input signal span (2V from conditioner to meter) resulting in a display value of the SCAL value set in the user

menu. The linear equation is y = mx + b where m = (SCAL-0)/(2-0) and b = oFSt.

The default value of SCAL is 2000, but it may be set to any value between -1999 and +9999.

The internal Signal Span is limited to 3 V DC between- 1 V DC to+ 2 V DC. Any outputs from an Input Signal Conditioning module

that exceed these limits will cause the meter to indicate overrange regardless of the Digital Display Span scaled. For example,

an ID01 DC Volts Input Signal Conditioner can read +/-2VDC, but in the DL-40 will show under-range for a -1.2V input.

STEP A Enter the Calibration Mode

1) Press the

and buttons at the same time.

Display toggles between [CAL] and [oFF].

2) Press and hold the or button.

Display changes from [oFF] to [on].

3) Press the

button. Display toggles between [CAL] and [out].

STEP B Select Between Calibration of Input or Output

Note: If the analog output option is not present, Step B is skipped and the

program goes directly from Step A to Step C.

1) Press the or button to select the display toggling from [CAL]

to [inPt].

2) Press the

button. Display toggles between [oFSt] and the

previous offset setting.

STEP C Set the Offset on the Digital Display

1) Using the and buttons, adjust the digital display to the

desired offset. This is the reading that the meter will display for a

zero input.

2) Press the

button. Display toggles between [SCAL] and the

previous Scale factor.

STEP D Set the Scale factor on the Digital Display

1) Using the and buttons, adjust the meter display to the

desired Scale factor. The default value is 2000, for which a 2V

input will read 2000. If the scale factor is changed the display will

change proportionately. Therefore if the Scale factor is changed

to 1000 then for the same 2V input the display would read 1000.

2) Press the

button.

The Digital Calibration Procedure Mode is Now Complete.

The menu branches to the DECIMAL POINT AND BRIGHTNESS SE

When the rear Auto/Manual switch is in the Auto position, the meter can be calibrated with an automatic scale factor calculation,

by applying a low input signal (InLo), entering the desired low display reading for that signal (ZERO), then applying a high input

signal (InHi), and then entering the desired high display reading (SPAN). The meter then automatically calculates and programs in

the requisite scale factor using a true linear (y=mx + b) calculation where m = (SPAN-ZERO)/(InHi-InLo) and b = ZERO, but within

the following parameters.

1. Positive and negative signals may be applied, but the difference between the high and the low signal inputs must be at least 1000

counts or Err will be indicated.

2. Positive and Negative values for the desired reading can be entered, but the scale factor created can not exceed the Digital

Display Span capability of the meter which is 12,000 counts between –1999 to 9999.

3. The internal Signal Span is limited to 3 V DC between – 1 V DC to + 2 V DC. Any outputs from an Input Signal Conditioning

module that exceed these limits will cause the meter to indicate overrange regardless of the Digital Display Span scaled.

Note: Most input signal conditioners have provisions for analog calibration and scaling. If the meter’s digital scale factor is set to

read zero with a zero input (shorted input), and to read 1000 with a 1.000 V input, any pre-calibrated signal conditioner with an

output that does not exceed – 1 V to + 2 V, will read correctly in the meter without any further calibration.

STEP A Enter the Calibration Mode

1) Press the

and buttons at the same time.

Display toggles between [CAL] and [oFF].

2) Press and hold the or button.

Display changes from [oFF] to [on].

3) Press the

button. Display toggles between [ZErO] and the

previous zero setting.

STEP B Select Between Two Point Digital Calibration of Input Signal and

Two Point Analog Output

Note: If the analog output option is not present, Step B is skipped and the

program goes directly from Step A to Step C.

1) Press the or button to select the display toggling from [CAL]

to [inPt] input calibration.

2) Press the

button. Display toggles between [ZErO] and the

previous zero setting.

STEP C Set the Meter’s Low Input Signal Reading on the Digital Display

1) Apply a zero or low signal to the meter.

(Positive or negative values are allowed)

2) Using the and buttons, adjust the meter display to the

desired reading for the applied low input signal.

3) Press the

button. Display toggles between [SPAn] and the

previous span setting.

STEP D Set the Meter’s High Input Signal Reading on the Digital Display

1) Apply a high input signal to the meter.

2) Using the and buttons, adjust the digital display to the

desired reading for the applied high input signal.

3) Press the

button.

The Digital Calibration Procedure Mode is Now Complete.

If the digital calibration was successfully completed, the menu

branches to the DISPLAY FUNCTION CONFIGURATION MODE,

(see page 7) and the display flashes [dP] and the previous setting.

ERROR Indicates Unsuccessful Calibration

If the calibration was unsuccessful, the display indicates [Err],

the new calibration settings just entered will not take effect and

the previously stored setting will remain.

The three most likely causes of an error during calibration are:

1) The full scale and zero signals were too similar. The full scale

signal must be at least 1000 counts greater than the zero or

low input signal (positive and negative values are allowed).

2) The scaling requirement exceeded the capability of the meter

(–1999 to 9999).

3) No input signal present, or incorrect connections.

The Modbus/RS-485 communication settings sub-menu allows

you to set the following parameters:

a) Baud Rate – this is the baud rate of the RS-485 serial communi-

cation between the meter (slave) and Modbus master. Options are

9600 (default, meter shows “96”) and 19200 (meter shows “192”).

b) Address – this is the meter’s Modbus address on the RS-485

loop. Typically, RS-485 limits the number of devices on the loop to

32, but the DL-40 supports the full Modbus address range of 1-247.

Address 1 is the default value.

c) Parity – this is the parity setting for the RS-485 serial commu-

nication between the meter (slave) and Modbus master. Options

are: None (display shows “0”; Odd (display shows “1”); Even

(default, display shows “2”).

The meter’s response time to a read command from the master is

40-45msec (typically 42msec). The response time for a write com-

mand is 70-75msec (typically 72msec). This is due to the module

having to communicate to the meter’s core firmware to complete

the desired command. Exception responses are handled directly

by the module and typically have a response time of 3msec.

Modbus RTU & RS-485 Communication Settings

The DL-40 Modbus communication module supports the following

Modbus commands:

a) Read Holding Register (0x03)

b) Write Single Register (0x06)

Modbus addresses for DL-40JANUS registers are shown on

the next page

The following are some things to note about particular registers:

a) Modicon address 40001 RELAY has the bit values for Sp3 &

Sp4 and LED3 & LED4 reversed. There is an historical reason

for this, and we have chosen to maintain backward compatibili-

ty in case customer’s want to send their meters in for a Modbus

upgrade (at a nominal fee).

b) Modicon addresses 40002 INP, 40026 PEAK, 40027 VALY,

40029 ZERO, 40029 SPAN return a 2 byte hexadecimal value

of the meter’s display (in counts) and does not include the deci-

mal point. If you need the decimal value with decimal point, you

will need to read the register, convert it to decimal, read 40024

(see below) to determine decimal location, then combine the

two. Display counts are in Two’s Complement notation.

a. Hex values for 0 to 9999 are 0x0000 to 0x270F.

b. Hex values for -1 to -1999 are 0xFFFF to 0xF831.

c. Over-range is indicated by a returned value of 9999

(0x270F).

d. Under-range is indicated by a returned value of -1999

(0xF831).

c) In order for Sp3 and Sp4 set point settings to work, the DL-40

must have the optional Output Carrier Board installed (P/N

SA-DL/OM-CB).

d) All Delay on Make (DoM), Delay on Break (DoB) and Hysteresis

values are in units of whole seconds.

e) Modicon address 40023 RLYMOD uses the following values

to set the relay activation mode (letter sequence is SP1, SP2,

SP3, SP4):

a. 0 for HHHH

b. 1 for HLHL

c. 2 for LHLH

d. 3 for LLLL

e. H means relay is energized if input is equal to or

exceeds setpoint; L means relay is energized if input

is less than setpoint.

f. Note that the meter will not show the last two letters if

the Output Carrier Board option is not installed.

f) Modicon address 40023 DP uses the following values to set the

display decimal point location:

a. 0 for XXXX (none)

b. 1 for XXXX.

c. 2 for XXX.X

d. 3 for XX.XX

e. 4 for X.XXX

g) Modicon address 40025 BRIGHT must be a value between 1

(most dim) to 4 (most bright).

h) Modicon addresses 40028 and 40029 will have different mean-

ings depending on the Auto calibration or Manual rescaling

operational selection (see Auto Calibration Mode or Manual

Rescaling Mode above). These are explained in the register

table below.

i) Modicon addresses 40030 IZERO and 40031 ISPAN return

hexadecimal values related to the Auto Mode calibration of the

meter. They do not necessarily match expected values due vari-

ations and tolerances in the measurement circuit components,

e.g., calibrating with a value of zero volts for the ZERO value

may return a value of 0xFFFE (-2). These registers have no

meaning in Manual Rescaling Mode).

2) Press the

button. Display toggles between [SP4] and the previous [SP4] setting.

STEP L Set Setpoint 4 (SP4) (No [doM] or [dob])

1) Using the and buttons, adjust the display to the desired SP4 value.

2) Press the

button. Display toggles between [HYSt] and 0.

STEP M Set the Hysteresis Setting for Setpoint 4

Using the and buttons, adjust the display to the desired hysteresis [HYSt] value.

2) Press the

button. Display toggles between [rLYS] and the previous relay setting.

STEP N Set Relay Activation mode [rLYS]

(H) High the relay energizes when the setpoint is exceeded. (L) Low the relay energizes

below the setpoint. The setpoint is indicated from left to right SP1, SP2, SP3, SP4.

1) Using the and buttons, adjust the reading on the display to the desired

relay settings: [LLLL], [LHLH], [HLHL], [HHHH].

If only 2 relays installed [LH--], [HL--], [HH--], [LL--].

Pinout Diagram

The Rear View of the Meter diagram shows the meter with the

relay configuration: dual 9 Amp Form C and dual 4 Amp Form

A relays. An analog output module is also shown as installed.

The DL-40JANUS uses plug-in type screw terminal connectors for

all input and output connections. The power supply connections

(pins 14 and 15) have a unique plug and socket outline to prevent

cross connection. The main board and input signal conditioner

use right-angled connectors as standard. The output module uses

straight-thru connectors as standard.

Auto-sensing AC/DC power supply. For voltages between

85-265 V AC / 95-370 V DC (PS1) or 18-48 V AC / 10-72 V DC (PS2).

WARNING: AC and DC input signals and power

supply voltages can be hazardous. Do Not connect live

wires to screw terminal plugs, and do not insert, remove

or handle screw terminal plugs with live wires connected.

Pin 16 Positive (+) analog output.

Pin 17 Negative (–) analog output.

Pins 18 to 21 – Rear Panel Function Pins

Pins 18 to 21 provide functions that can be implemented

with an external switch. Their pin definitions are:

Pin 18 DIM. By connecting the display dim (DIM) pin to

the COMMON pin, the display brightness setting

is halved.

Pin 19 COMMON. To activate the LOCK or DIM

functions from the rear of the meter, the

respective pins have to be connected to the

COMMON pin. This pin is connected to the

internal power supply ground.

Switch 1 AUTO/MANUAL SCALING Mode. When

switch 1 is set to ON position, the Manual

Scaling is selected. When switch 1 is set to OFF,

the Auto Scaling is selected, and this is

the default position.

Switch 2 LOCK. By setting the LOCK pin to the ON

position, the meter's programmed

parameters can be viewed but not changed.

Input Signal – Pins 1 to 6

Pins 1 to 6 are reserved for the input signal conditioner.

See the data sheet for the selected input signal conditioner.

Pins 8 to 12 – Relay Output Pins

Note: If relays for setpoints 1 & 2 are installed on the

main board, and a relay output module is used that also

has relays in the setpoints 1 & 2 positions, the duplicate

relays will operate in unison.

Pin 8 SP1 NO. Normally Open 5 Amp Form A.

Pin 9 SP1 NO.

Pin 10 SP2 NO. Normally Open 5 Amp Form A.

Pin 11 SP2 NO.

Pin 12 NO CONNECTION.
