General Alarm Contact [Std] – This is
provided for the customers use. A normally open
contact will close when the compressor is in
operation. If a shutdown or trip occurs this
contact will return to its normally open state.
PORO Relay [Std] – The controller will
energize the PORO relay (FR1) that is
connected to terminal XO6 pins 1 and 2. This
electronic relay is used to sound the horn
mounted on the compressor package by closing
the auxiliary contact FR1-1 which will supply 120
volts AC to the PORO Horn. This horn warns the
surrounding area that the compressor is about to
start after a power outage or before a scheduled
start. For PORO this relay should be energized
immediately when power is restored and
remains energized until the PORO timer expires
and the compressor actually starts. For
scheduled starts, this relay will be energized for
10 seconds prior to the unit starting.
