Diagnostic Test Procedures
The diagnostic procedures perform basic functional
tests to verify the operation of the front panel indicators,
inputs, and outputs, and the communication ports.
These tests are performed in relay test mode, which
is entered in the following manner:
▲
CAUTION:
The Diagnostic Mode is intended
for bench testing the relay only. Do not use the
diagnostic mode in relays that are installed in an
active protection scheme.
For units with the optional HMI panel:
1. Press the
ENTER
pushbutton.
2.
If Level Access is active, the following is
displayed:
ENTER ACCESS CODE
0
a. Input the required Access Code,
then press
ENTER
.
b. If the proper Access Code has been
entered, the HMI will return:
LEVEL #(1,2 or 3)
Access Granted!
VOLTAGE RELAY
VOLT curr freq v/hz
c. Go to step 4.
3.
If Level Access is not active, then the
following is displayed:

Equipment and Test Setup
No calibration is necessary, as the M-3311A
Transformer Protection Relay is calibrated and
fully tested at the factory. If calibration is necessary
because of a component replacement, follow the
Auto Calibration procedure detailed in Section 6.3.
Required Equipment
The following equipment is required to perform the
test procedures outlined in this chapter:
•
Two Digital Multimeters (DMM) with a
10 Amp current range. These are not
required if using a Pulsar Universal Test
System.
•
Appropriate power supply for system
power.
•
Three-phase source capable of 0 to 250
V ac. (Pulsar Universal Test System or
equivalent.)
•
Three-phase current source capable of 0
to 25 Amps. (Pulsar Universal Test System
or equivalent.)
•
Electronic timer with a minimum accuracy
of 8 msec. (Pulsar Universal Test System
or equivalent.)
Equipment Setup
▲
CAUTION
: The proper voltage range for the relay
is clearly marked on the power supply label affixed
to the rear cover.
1. Connect system power to the Relay
Power Supply:
a. PS1 Terminals 62 (hot) and 63
(neutral)
b. PS2 Terminals 60 (hot) and 61
(neutral)
2. Connect the voltage and current sources
as indicated in the configuration listed in
the individual function test procedure.
