Sys Temp
Total # Pumps The total number of pumps in the system.
4.2.1
Factory Set
# Jockey
Jockey pumps will always be first in the staging sequence.
4.2.1
0
Pumps
Alternation will not change this designation. Jockey Pumps
will be assigned to the lowest pump numbers starting with
Pump # 1.
# Standby
A standby pump will only operate if a duty pump fails.
4.2.1
0
Pumps
The last pumps in the staging sequence will be designated
as the standby pumps.
HP
Enter the horsepower from the nameplate of the motor.
4.2.2
Actual
These values are required for power staging.
Amps
Enter the full load amps from the motor nameplate.
4.2.2
0
These values are required for amps staging.
GPM
Enter the maximum GPM from the pump nameplate.
4.2.2
0
These values are required for flow staging.
Pri Stg Mthd
Primary staging method. Power, Amps, and flow staging
4.3.1.1
Power
require nameplate data to be set up. See section 4.2.2.
Stg (primary)
The value at which pumps will stage on. The units depend on
4.3.1.1
80
the staging type. This is the stage 1-2 value and will be used for
each staging occurrence unless Dynamic Stg is set to “Y”.
Dstg (primary) The value at which pumps will stage off. The units depend on
4.3.1.1
72
the staging type. This is the destage 2-1 value and will be used
for each destaging occurrence unless Dynamic Stg is set to “Y”.
PT (primary)
The proof timer, in seconds, that will elapse before staging
4.3.1.1
5
pumps on/off.
Dynamic Stg
Select “Y” for Dynamic Stg to choose different staging and
4.3.1.1
N
(primary)
destaging values for each staging occurrence. A separate
screen will be displayed to allow for these inputs.
Sec Stg Mthd
Secondary staging method. This will be used if the sensor
4.3.1.2
Pressure
for the primary method fails. Power, Amps, and flow stag-
ing require nameplate data to be set up. See section 4.2.2.
Stg (secondary) The value at which pumps will stage on. The units depend on
4.3.1.2
System
the staging type. This is the stage 1-2 value and will be used for
Pressure – 10
each staging occurrence unless Dynamic Stg is set to “Y”.
Dstg
The value at which pumps will stage off. The units depend on
4.3.1.2
System
(secondary)
the staging type. This is the destage 2-1 value and will be used
Pressure – 3
for each destaging occurrence unless Dynamic Stg is set to “Y”.
