1.3.4 General Plant Performance Specifications
The SAGEON PSMC I was designed to operate in accordance with the monitor and control
specifications portion of TR-EOP-000154, for +24 and -48 Vdc Power Plants.
1.3.5 Safety Specifications
Underwriters Laboratory Standards of Safety for Information Technology Equipment (UL
1950) and the Bellcore Network Equipment-Building System Generic Equipment
Requirements (TR-EOP-000063) were adhered to in all component and wire selection.
Particular attention was paid to safety ratings and OI-28 flammability requirements.
1.3.6 Monitoring Specifications
* See PN Drawings and Menu Flow Charts, located in the back of this manual, for electro-
mechanical details and user menu information.
•
The front panel meter of the SAGEON PSMC I is an alphanumeric LCD display. It
displays voltage with 0.05 % accuracy (10mV; within one least significant digit of
display), current readings with +/-0.2% accuracy and temperature readings within 1/2
o
F.
•
The information displayed (in the default mode) on the front panel of the SAGEON
PSMC I is plant voltage, plant current, and the number of active alarms. When the
Load Voltage channel has been enabled, the front panel will change to show the plant
voltage, load voltage, current, and the number of active alarms. If an ambient
temperature sensor is attached, it can be set up to toggle display with the plant current
on the default screen (CONFIGURE MENU). Optionally, the sum of the feeder
currents can be shown in place of the plant current if the “SUM” feature is selected
from the idle display configuration menu.
•
Four front panel push buttons provide access to all menus for general channel
polling, alarm status determination, system configuration, calibration, and testing.
•
15 analog channels predefined for plant voltage, plant current, load voltage, 9 feeder
and/or rectifier shunts, and three temperature sensors (ambient & 2 battery string).
•
5 binary fuse alarm (FA) inputs for Charge, Discharge, Sense/Control, Battery, and
Spare used for monitoring fuse and breaker status (battery level active/blown).
•
16 binary rectifier fail (RFA) inputs for monitoring individual rectifier status (active
low/GND closure).
•
2 binary counter-emf cell inputs for CEMF cell status (active low/GND closure).
•
2 binary inputs: one for LVD alarming and one Controller-Inhibit (active low/GND
closure).
•
Test jacks for manual confirmation of voltage, current, and temperature readings.
Test jacks are for reference only; proper calibration of the Sageon PSMC I should use
measurements at the screw terminals. E.g. Due to internal inline-protection of the
