Targets/Indicators
Five diagnostic LED indicators are provided.
POWER:
Green LED (normally ON) to indicate power supply is operating.
CLOCK:
Green LED (normally OFF) turns ON to indicate that the clock needs to
be set.
50PU:
Red LED (normally OFF) turns ON to indicate one or more of the inputs
has exceeded the pickup level(s).
ALARM:
Red LED (normally OFF) turns ON to indicate problems. Output A
(ALARM) de-energizes (closes) when ALARM LED is ON.
TARGET:
Red LED (normally OFF) turns ON if one or more of the relay outputs
has been energized. (If programmed by the PTARGET command.)
Keypad
Five keys are used to access information on the display and enter settings.
Communications
Only one communication port can be active at any time.
Front panel connector:
RS-232, 9-pin, female, D-sub DCE
Rear panel connectors:
RS-232, 9-pin, female, D-sub DCE
RS-485, 3-position terminal block
Baud Rate:
300, 600, 1200, 2400, 4800, 9600, and 19200
Buffer Size:
40 characters
Protocol:
ASCII and binary data transmissions
Power Supply
Power for the internal circuitry may be derived from ac or dc external power sources. Power supply data
is provided in Table 1-5.

Isolation
All output and power supply terminals have MOV suppressors. Maximum applied voltage must be no
greater than 300 volts where MOV suppressors are used. Surge suppression capacitors are installed
between terminal pairs and between terminals and chassis ground. When testing with 1,500 Vac, leakage
current (approximately 8 milliamperes per terminal) is expected. 1.500 Vac (RMS) at 45 to 65 hertz for
one minute or 2,121 Vdc may be applied between circuit groups, and between circuit group and chassis
ground in accordance with IEC 255-5 and ANSI/IEEE C37.90-1989 (Dielectric Tests).
Surge Withstand Capability
Qualified to ANSI/IEEE C37.90.1-1989, Standard Surge Withstand Capability (SWC) Tests for Protective
Relays and Relay Systems. Note: This qualification does not include the front RS-232 communication
port.
