Control Card Inputs
Identification Description
Start/Stop
12/24 VDC
or
115/230 VAC
Programmable Input, Control Input 1. (S1, S0)
Application of a voltage between S1 and S0 will either SET (normal logic sense)
or CLEAR (inverted logic sense) the parameter mapped to by parameter P65.
Removal of this voltage will either CLEAR (normal logic sense)
or SET (inverted logic sense) the parameter mapped to by parameter P65.
Default setting is P52, Bit 4: Start/Stop, which is active
only when the operator selects and enters REMOTE STARTING at the keypad.
The application of a voltage, as specified, between these terminals, will initiate a START.
The removal of this voltage will initiate a STOP.
Control Card Outputs
Identification Description
12, 14, 11
Programmable Output, Relay K1.
A bit = 1 on the parameter/bit selected by P57 makes Relay K1 ACTIVE (normal logic sense)
or INACTIVE (inverted logic sense).
Default setting is P52, Bit 5: Main Contactor
Relay change-over contacts:
Contact rating: 230VAC, 3A, AC1 ; 24VDC, 3A
11 – Common; 12 – Normally-closed; 14 - Normally-open
22, 24, 21
Programmable Output, Relay K2.
A bit = 1 on the parameter/bit selected by P59 makes Relay K2 ACTIVE (normal logic sense)
or INACTIVE (inverted logic sense).
Default setting is P8, Bit 3: Top of Ramp or Full Volts
Relay change-over contacts:
Contact rating: 230VAC, 3A, AC1 ; 24VDC, 3A
21 – Common; 22 – Normally-closed; 24 – Normally-open
