SYSTEM CONFIG
(see Section 6.5 , System
Configuration for detailed
information)
Sets the system configuration.
0 = RUN/STOP control using AUX1 and AUX2. Both AUX1 and
AUX2 must have a contact closure to run.
By default, AUX1
and AUX2 are programmed to be always ON. See
parameters AUX1 SELECT and AUX2 SELECT to change this
setting.
1 = Analog constant pressure control.
2 = Motor speed control proportional to 0-5VDC analog signal
(speed potentiometer).
3 = Motor speed control proportional to 4-20mA analog signal.
4 = Analog constant pressure (4-20 mA only) with HOA switch
and motor speed control by potentiometer.

TROUBLESHOOTING Factory assisted use only. Contact manufacturer. 0/0/5
PASSWORD SETUP
Allows keypad functionality to be password protected. When
keypad is locked, parameters and values can be viewed but not
changed. Parameter value of zero disables password
protection. Use arrows to scroll to a value that will become the
password.
0/0/99
ANALOG SELECT
Reverses the scale of the analog signal, both 0-5VDC and 4-
20mA.
NO/NO/YES
PROGRAM RELAY 1
Programmable normally open relay. Control terminals COM,
1NO. The relay can be programmed to change state for the
following conditions:
0 = System Fault
Closed = normal, Open = fault
1 = Reserved
2 = Reserved
3 = Reserved
4 = Pump Fault e.g. motor overload, dry well, etc.
Closed = normal operation, Open = fault
5 = Minimum Frequency. Relay changes state when motor
frequency is greater than the value set by parameter
MIN
FREQUENCY . (see Note 1, next page)
When lead/lag pump control has been selected, it will override
programmable Relays 1, 2.
6 = Jockey Pump. Relay will not participate in lead/lag or
multiplex pump control. Instead, relay will close when motor
frequency is greater than 0, and open when it is exactly 0.
This setting is only available for Relay 1.
0/0/6
PROGRAM RELAY 2
Programmable normally open relay. Control terminals 2NO, 2C.
See Parameter
PROGRAM RELAY 1 above for description of
values.
0/0/5
ANALOG IN REVERSE
Reverses the scale of the analog signal, both 0-5VDC and 4-
20mA. For example, in normal 0-5VDC signal, 0V = low and 5V
= high. In reverse, 5V = low and 0V = high.
NO = normal, YES = reverse
NO/YES
