Communications

Both dry contacts (relays) that indicate status and a Serial Communications Port

(RS-232) are available for monitoring the HC-DySC.

Dry Contacts

Three relay contacts indicate HC-DySC status. The contacts are form A and

close upon occurrence of the named event: (a) any SAG EVENT, when rms input

voltage drops below 88.5% of rated value; (b) OUTPUT OK, when output

voltage remains between 87% and 110%; and (c) a system ALARM event. The

relay contact ratings are 24V at 1A.

For access, remove the small metal cover from the top of the HC-DySC

(See Figure 6

• All wiring is to be Class 2, limited to 24 Volts, AC or DC.

• Acceptable wire gauges range from 24AWG to 12AWG (0.205-2.5mm2).

• Torque connections to 5.0 lb-in (0.6 N-m).

• For permanent installation of communications conductors, a standard

conduit knockout is located on the cabinet top (See Figure 2
