DESCRIPTION
DEFAULT [UNITS]
(MIN - MAX)
1.3.4 Program Relay
No 1
Programmable normally open / normally closed relay. Control
Terminals 1NC, 1NO, and COM. The relay can be programmed to
change state for the following conditions:
0 = System Fault: State will change when drive faults.
1 = Lag Pump: Lag/Duplex is controlling the relay.
2 = Modbus Control: Customer Modbus is controlling the relay.
Modbus Control commands will override current settings except
when configured to state 1 or 7.
3 = Pump Fault: e.g. motor overload, under current, etc.
4 = Output Active: Relay activates when VFD frequency is greater
than zero.
5 = Damper: Relay activates when AUX1 is closed in the Auto run-
mode.
6 = Pre-lube Oiler: Relay energizes when a RUN command is
given in either Manual or Auto mode. The drive will count down from
1.3.30 OILER ON-DELAY TIMER and then begin outputting. Once
the drive reaches 1.1.1 MIN FREQUENCY, the relay will de-
energize.
7 = Jockey Pump. Relay will not participate in lead/lag or multiplex
pump control. Instead, relay will change states when motor
frequency is greater than 0, and open when it is exactly 0. This
setting is only available for Program Relay 1.
0 (0-7)
1.3.5 Program Relay
No 2
Programmable normally open / normally closed relay. Control
Terminals 2NC, 2NO, and COM. See Parameter 1.3.4 PROGRAM
RELAY 1 above for description of values.
0 (0-6)
1.3.6 Program Relay
No 3
Programmable normally open relay. Control Terminals 3NO, 3C.
See Parameter 1.3.5 PROGRAM RELAY 2 above for description of
values.
0 (0-6)
1.3.7 Program Relay
No 4
Programmable normally open relay. Control Terminal 4NO, 4C. See
Parameter 1.3.5 PROGRAM RELAY 2 above for description of
values.
0 (0-6)
1.3.8 AUX1 Select
1.3.9 AUX2 Select
Programmable digital inputs. Generally used for motor Run/Stop
control.
0 = RUN/STOP (closed = RUN, open = STOP)
1 = RUN/STOP (open = RUN, closed = STOP)
2 = Always in Run Mode
3 = Latching Relay. When the connection between the AUX
terminal and COM is opened the drive will stop the motor and
display a fault on the screen. The motor will remain stopped even
if the connection is closed. The fault must be cleared by pressing
the ENTER key.
The function of these inputs can change when certain System
Configuration settings are chosen. See Section 5.5.
When the drive is in AUTO mode and stopped, the display will
show:
A1█ A2_ A3█ A4_
The symbol _ indicates that the input is off and the symbol █
indicates the input is on. In the example above, AUX1 and
AUX3 are on.
