Communications
Both dry contacts (relays) that indicate status and a Serial Communications Port
(RS-232) are available for monitoring the ProDySC.
Dry Contacts
Three relay contacts indicate ProDySC 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 1 amp.
For access, remove the small metal cover from the top of the ProDySC
(SeeFigure 9
).
A removable connector (plug) is provided to facilitate wiring.
All wiring is to be Class 2, limited to 24 Volts, AC or DC.
Acceptable wire gauges range from 24AWG to 12AWG (0.2-2.5mm
2
).
Torque connections to 4.5 - 5.3lb-in (0.5 - 0.6 N-m).
For permanent installations, a standard conduit knockout is located within
the wiring area (SeeFigure 9
).
