PUMP CALL SEQUENCE - Setup Parameters
9
The following is a description of each of the Setup Parameters used to establish the Pump Call Sequence:
Note: Discrete Inputs programmed with Functions 1-4, 6-7, 9-12, and 13-16 are also available to establish or modify the
Pump Call Sequence. See the description of these Discrete Input Functions on pages 14-16.
Number of Pumps Present - Parameter P.13
This Parameter establishes how many pumps are available at the Lift Station to perform level control.
Simplex (1 pump) Duplex (2 pumps) Triplex (3 pumps) Quadraplex (4 pumps)
Number of Pumps Allowed to Run at the Same Time - Parameter P.14
In cases where there is an inadequately sized discharge pipe, or inadequate electrical power, running all available
pumps at the same time may be a problem. This Parameter is used to set an upper limit on the number of pumps
called to run at the same time. If there is no need for this feature P.14 may be left on it’s default value of 4.

Number of Pumps Allowed to Run On Generator - Parameter P.15
In cases where the Emergency Generator is not sized large enough to run all the available pumps, this Parameter
is used to set an upper limit on the number of pumps called to run on the Generator. There must be a contact from
the Transfer Switch connected to one of the Controller’s Discrete Inputs and it must be programmed for Function 7.
If there is no need for this feature Parameter P.15 may be left on it’s default value of 4.

Alternator Sequence Mode - Parameter P.16
This Parameter is provided to allow the Controller to accommodate a variety of special sequence requirements.

Alternator Sequence Mode
1 = Standard Alternation See Page 11.
2 = Pump 1 Always Lead - Stays On With Other Pumps See Page 11.
3 = Pump 1 Always Lead - Turns Off With Other Pumps See Page 12.
4 = Split Alternation - Pumps 1&2, and Pumps 3&4 See Page 12.
5 = Fixed Sequence - Pump 1 Always Lead See Page 13.
6 = Stepped On/Off - Only One Pump Runs at a Time See Page 13.
