J22

Description

sync input. It connects to the cathode of an LED at the input of an optocoupler. Refer to

J22-32.

AMP SHARE B

PARALLEL

CL ENA

MR C: Phase C master signal

MR A: Phase A master signal

CS C: Phase C current sum

CS A: Phase A current sum

OSC C: Phase C oscillator output

OSC A: Phase A oscillator output

CL C: Phase C current limit reference

CL A: Phase A current limit reference

D COM: Digital Common

RNG HI: Voltage range state: Logic HI = high range, LOW = low range

: Overload

FLT B: Phase B current limit fault control

F STB HI: Function Strobe / Trigger output HI. A low-going pulse, >400 s, that indicates

voltage or frequency change. Isolated output that requires a pull-up resistor, 22K , to +5

VDC. Use J22 pin 14 (F STB LO) for common. See section 3.6.5 for details.

EX SYNC HI, External Sync input HI. This is an input that can be used to synchronize the

outputs of the AC Power System. This input requires a logic high level of at least +4.5

VDC at 5 mA. The input should have a duty cycle 50 30%. J22-15 is the common input.

The External Sync input is optically isolated. It must be enabled from the SNC screen.

FLICKER /

REMOTE ON: This is a logic input that can be used to remove the programmed output

voltage. A logic low on this pin will cause the output voltages to be programmed to 0.0

volts and the output relays to open. A logic high will cause the programmed output

voltage to be restored at the output terminals. A contact closure between this pin and

J22-27 (D COM) will simulate a logic low state.
