The system reset pushbutton resets the OIC multibus key-
board module (IIMKM02A) to an initial power up condition
when pressed.
A terminal block connects annunciators to user-defined
alarms. The terminal designation is printed on the panel
beside the terminal. The digital in (DI) and digital out (DO) ter-
minals are not used.
The power indicator is lit when the AC power is connected to
the power entry panel and the main power circuit breaker is
on.
Either 120 or 240-VAC power is used to supply power to the
IIOIC42 operator interface console. The AC in is either hard
wired (IIOIC422 model) or uses a 3-prong plug connector on
the power entry panel.
NOTES:
1. Use the AC outlet for the intended purpose only.
2. Refer to Section 3 for wiring and cable connections. Some of
the connections are on the back of the power entry panel and are
accessed through the door on the back of the OIC console.
