This quad channel thermocouple con-
troller is ideal for numerous industrial
temperature applications. It accepts di-
rect sensor input from all common ther-
mocouple types.
One of the key features of this controller
is its ability to average the inputs across
2, 3 or 4 temperature channels, and use
this averaged value for a display source
or for setpoint activation.

2.2 - Display brightness
To adjust the display brightness, press the and buttons together from the
main display. BRI appears and toggles with the current setting. Use the and
buttons to adjust the LED backlight, and then press to nish.

pear in the order shown in the table below, and will cycle continuously at each press
of the or button.
Press at any time to return to normal operating mode. PEAK and VALLEY may be
reset to zero by pressing the and buttons at the same time while the variable
is being displayed.
Up and down button shortcuts
PEAK The maximum measured value since the instrument was turned on or reset
(see 5.5)
TEMP 1 Current input value for channel 1
TEMP 2 Current input value for channel 2
TEMP 3 Current input value for channel 3
TEMP 4 Current input value for channel 4
VALLEY The minimum measured value since the instrument was turned on or reset

3.2 - Analog input
See 3.1D
Wire the analog input module as shown, referring to the
product label. The unit accepts input from up to four ther-
mocouple sensors. (To use less than four sensors, select
your number of sensors in 6.2D.)
TC3TC2TC1 TC4
Note that you must start wiring from channel 1. (I.e. For 2 channels, use CH1–2, not CH3–4).
3.3 - Relay outputs
See 3.1A
If your controller has relay
outputs tted, wire them as
shown. Relays can be pro-
grammed to operate within
the total span range of the
controller.

Note that if you have activated the multiplex feature by setting your analog output
source to MPX in 6.6B, then the 'Pk/Val' and 'Hold' pins will not perform the func-
tions described above. (See 5.4C for more information.)

3.7 - Power supply
See 3.1F
DO NOT attempt to wire your controller while the power is on. NEVER connect your
low voltage controller to mains power.
Wire your controller for low or high voltage power supply, as show in the diagrams
below. Check the label on the unit against the colour of the connector:
›Orange =
High voltage (85–265V AC,
95–370V DC)
›Black =
Low voltage (15–48V AC,
10–72V DC)

4.2 - Installation instructions
A Prepare the Panel Cutout to
92 x 45mm ±.5 (3.62 x 1.77" ±.02),
as shown below.
Allow at least 155mm (6.10")
depth behind the panel to accom-
modate the meter body, protrud-
ing connectors and cabling.
B Remove the Mounting Clips from
the meter back.
C Slide the Panel Gasket over the
rear of the unit to the back of the
Meter Faceplate.
D From the front of the panel, insert
the meter into the Panel Cutout.
Holding the unit in place, engage
the Mounting Clips so that the tabs
snap into place over the notches on
the case.
E To achieve a proper seal, tighten
the Screws evenly until the unit sits
rmly against the panel. Do not
over-tighten the screws.

5 DATA SOURCES
5.1 - Available data sources
The table below shows the data sources that are available for the various controller
outputs. See 5.2–5.5 for more information.
Display SP Analog O/P Serial O/P Peak/Valley
DISP
AUTO
TEMP 1–4
AVETMP
MAXTMP
MINTMP
MPX
PEAK

5.2 - Display
The data source for the Display determines what will be displayed on the screen
when the controller is in normal operating mode - you can set this in 6.3B.
Most of the available data sources can be selected (see 5.1). You can also select
'AUTO', which will cause the display to cycle continuously through the four
temperature input channels.
While 'Display' has its own data source, it can also be used as a data source - for a
setpoint, the analog output, the serial output, or the peak and valley values. This will
essentially mirror the display data source to the selected output, allowing the cycling
'AUTO' feature to be used with other outputs, if desired.
