Two types of Power Input Modules (PIM) can be used with the System Monitor. The PIM shown
below on the left is supplied when the Serial Interface option is specified. It includes the two
additional 25-pin serial connectors. The PIM on the right is the standard input module, Whenever
the PIM is referenced pictorially in this document, the figure shown is the Serial Interface option
PIM. In all these figures, the standard PIM may be substituted for the Serial Interface PIM. All
connections to either PIM are the same, only the style of the connectors have been altered.

System Monitor 80175-01
I2 I MONITOR FUNCTIONS I
SYSTEM POWER-UP INHIBIT
The System Monitor provides a Power-up Inhibit function that allows each monitor to inhibit its
alarms during power-up, or whenever a system supply voltage falls below its operating level. After
power-up, the inhibit function remains active for approximately 2 seconds. The inhibit function can
also be activated by contact closure through terminals on the Power Input Module at the rear of
the rack.
SUPPLY VOLTAGES OK
Seven LEDs located behind the front panel of the System Monitor are ON to indicate when supply
voltages are functioning. The supply voltages are +VRH, +VRL, +7.5V, +5V REF, -7.5V, and -
VT. A green LED on the front panel (SUPPLIES OK), when ON, indicates that all supply voltages
are functional.
SYSTEM RESET
The System Monitor provides System Reset capability that is activated by either external contact
closure through terminals on the Power Input Module, or by pressing the RESET switch on the
front panel.
TRIP MULTIPLY
The System Monitor provides a trip multiply control that is activated by contact closure through
terminals on the Power Input Module. When activated, trip multiply allows the alarm setpoints to
be multiplied by a factor preset on monitors with Trip Multiply options installed. The Trip Multiply
function is indicated by a red LED on the front panel.
STATIC DATA BUS BUFFER
The System Monitor multiplexes signals from the Communications Processor to select static data
from the monitors. Static data signals from the monitor are buffered before being sent to the
Communications Processor. If the Serial Interface option is installed, the position and data select
signals from the Communications Processor are intercepted in the interface. If no Communications
Processor is connected the Serial Interface takes over control of the position select and data
select signals to gather data.
OK RELAY
The System Monitor drives an OK Relay that is located on the Power Input Module. The single-
pole, double-throw (SPDT) relay is used to indicate that the 3300 rack is in an OK condition. The
OK Relay is set normally energized. The OK Relay is deactivated either by the system power-up
inhibit signal (from System Monitor), or by a not OK signal from the monitors.

I2 I MONITOR FUNCTIONS
ALARM SETPOINT ADJUST
System Monitor 80175-01
I110
The System Monitor has two switches on the front panel that adjust alarm setpoint levels on each
monitor. One switch is for upscale adjustments and the other is for downscale adjustments.
KEYPHASORS
The System Monitor receives input from two Keyphasor transducers through terminals on the
power input module and buffers the input for use by the monitors. Buffered Keyphasor signals are
also available from the coaxial connectors on the front panel. The System Monitor also provides
short-circuit protected Keyphasor power.
SERIAL INTERFACE OPTION
When installed in the System Monitor, the Serial Interface option provides a communications
interface via defined protocols for the transmission of static data from the 3300 rack. The Serial
Interface option can operate concurrently with a connected Data Manager Communications
Processor.

Communications processor systems used with 3300 systems should all
operate from the same power source. If they do not and if the 3300 system
power goes off, the computer screen will indicate system OK and displayed
meter values will be approximately 7% of full scale.
