Mode Last. (External circuitry must be connected to Discrete Inputs

on the Controller, to signal when a pump is in the Bypass Mode.)

oPr Operating Program Revision Number

ALTERNATION SEQUENCE SETUP

STANDARD ALTERNATION P.16 = 1

Notes:

•Unless there is some special circumstance that

requires a more complicated pump call sequence, this

is the sequence that should be used.

•Parameter P.17 must be used to select either First

On Last Off or First On First Off.

•Discrete Inputs programmed as Pump 1-4 Disable

inputs may be used to disable pumps.

•Discrete Inputs programmed as Call Pump 1-4 Last

inputs may be used to assign pumps to standby status.

•Discrete Inputs programmed as Sequence Inputs 1-4

may be used to set the lead pump.

•A Discrete Input programmed for External

Alternation may be used to force alternation. When

this feature is used, Automatic Alternation would

normally be disabled by setting Parameter P.18 to

Disabled.

•If connected to a SCADA system, alternation may be

initiated by momentarily setting Coil 136 high, or by

forcing the lead pump by writing to Register 40022.

PUMP 1 ALWAYS LEAD P.16 = 2

Stays On With Other Pumps

Notes:

•This sequence is used when it is required that pump 1

always be lead pump. This sequence keeps pump 1

on, when the other pumps are called to run.

•Parameter P.17 must be used to select either First

On Last Off or First On First Off.

•Discrete Inputs programmed as Pump 1-4 Disable

inputs may be used to disable pumps.

•Discrete Inputs programmed as Call Pump 1-4 Last

inputs may be used to assign pumps to standby status.

•Discrete Inputs programmed as Sequence Inputs 1-4

may be used to set the lead pump.

•If pump 1 is disabled another pump will be called in

its place.

•A Discrete Input programmed for External

Alternation may be used to force alternation. When

this feature is used, Automatic Alternation would

normally be disabled by setting Parameter P.18 to

Disabled.

•If connected to a SCADA system, alternation may be

initiated by momentarily setting Coil 136 high, or by

forcing the lag pump by writing to Register 40022.

PUMP 1 ALWAYS LEAD P.16 = 3

Turns Off With Other Pumps On

Notes:

•This sequence is used when it is required that pump 1

always be lead, and when it must be turned off when

another pump(s) comes on. When a pump from the

second group is required, pump 1 is first turned off, then

after the Lag Pump Delay, the other pump is turned on.

•Parameter P.17 must be used to select either First On

Last Off or First On First Off.

•Discrete Inputs programmed as Pump 1-4 Disable

inputs may be used to disable pumps.

•Discrete Inputs programmed as Call Pump 1-4 Last

inputs may be used to assign pumps to standby status.

•Discrete Inputs programmed as Sequence Inputs 1-4

may be used to set the lead pump.

•If pump 1 is disabled, another pump will Not be called in

its place. The 1ST Pump On/Off Level parameters are

dedicated to pump 1 and will not call another pump.

•A Discrete Input programmed for External Alternation

may be used to force alternation. When this feature is

used, Automatic Alternation would normally be disabled

by setting Parameter P.18 to Disabled.

•If connected to a SCADA system, alternation may be

initiated by momentarily setting Coil 136 high, or by

forcing the lag pump by writing to Register 40022.

SPLIT ALTERNATION P.16 = 4

Notes:

•This sequence is used when it is required that pumps be

alternated in two separate groups.

•Parameter P.17 must be used to select either First On

Last Off or First On First Off.

•Discrete Inputs programmed as Pump 1-4 Disable

inputs may be used to disable pumps.

•Discrete Inputs programmed as Call Pump 1-4 Last

inputs may be used to assign pumps to standby status.

•Discrete Inputs programmed as Sequence Inputs 1-4

may be used to set the lead pump.

•If pumps from group 1 are disabled, then pumps in group

#2 may be called to take their place.

•A Discrete Input programmed for External Alternation

may be used to force alternation. When this feature is

used, Automatic Alternation would normally be disabled

by setting Parameter P.18 to Disabled.

•If connected to a SCADA system, alternation of

Group #1 may be initiated by momentarily setting Coil

136 high, or by forcing the lead pump position by

writing to Register 40022.

FIXED SEQUENCE P.16 = 5

Notes:

•This sequence is used when no alternation is required and

when pump 1 should normally be lead pump. Other pumps

may be set as lead by setting parameter P.39.

•Discrete Inputs programmed as Pump 1-4 Disable inputs

may be used to disable pumps.

•Discrete Inputs programmed as Call Pump 1-4 Last inputs

may be used to assign pumps to standby status.

•Discrete Inputs programmed as Sequence Inputs 1-4 may

be used to set the lead pump.

•The Pump Stop Mode (Parameter P.17) has no effect on

this sequence.

•Automatic Alternation Enable/Disable (Parameter P.18)

has no effect on this sequence.

•The External Alternation feature will not function when

using this sequence.

•If connected to a SCADA system, the lead pump

position may be set by writing to Register 40022.

STEPPED ON/OFF SEQUENCE P.16 = 6

Only One Pump Runs at a Time

Notes:

•This sequence is used in stations where there is a significant

difference in the size of the pumps, and when only one pump

is to be allowed to run at a time. When there is a need for

more pumping, the smaller pump is turned off and the next

larger pump is called to run. As the need for pumping

decreases, the larger pump is turned off and a smaller pump

is called to run in its place (provided the Off Levels are

staggered).

•The Lag Pump Delay operates to give the check valve of

the pump being turned off time to close before another pump

is called to run.

•Discrete Inputs programmed as Pump 1-4 Disable inputs

should be used to disable pumps. It is critical that the largest

pump in the group have some type of pump fault logic

connected to the respective Pump Disable discrete input.

•Discrete Inputs programmed as Call Pump 1-4 Last will not

function when using this sequence.

•Discrete Inputs programmed as Sequence Inputs 1-4 will

not function when using this sequence.

•The Pump Stop Mode (Parameter P.17) has no effect on

this sequence.

•Automatic Alternation Enable/Disable (Parameter P.18)

has no effect on this sequence.

•The External Alternation feature will not function when

using this sequence.

•The On Generator (Parameter P.15) has no effect on this

sequence.

SYSTEM STATUS

High Level Alarm:

•Upon a High Level Alarm, the indicator will come on and the relay contacts will close.

•A High Level Alarm is delayed for ten seconds after power is applied.

•The High Level Alarm relay contacts will be closed when there is no power on the controller.

•The moment electrical power is applied to the controller, the High Level Alarm relay contacts open.

•The High Level Alarm relay contacts will close if there is a complete failure of the controller.

•A High Level float may also be used to activate alarm. The discrete input used must be assigned function 18 or 38.

Low Level Alarm:

•Upon a Low Level Alarm, the indicator will come on and the relay contacts will close.

•A Low Level Alarm is delayed for thirty seconds after power is applied.

•The Low Level Alarm relay contacts will be open when there is no power on the controller.

•A Low Level float may also be used to activate alarm. The discrete input used must be assigned function 17 or 32.
