Test Connections:
Connect the relay High Voltage Closing contacts to
STOP/MONITOR
gate. Connect the
230 V / 4 A
,
AC CURRENT MAIN
to the Relay A Phase potential coil and the
COMMON return to Relay B Phase potential coil. Connect the
AC AUX
red output
terminal to Relay C Phase potential coil and the Black COM (common) return to Relay B
Phase potential coil.
Pick Up High Voltage Contacts:
4. Press
the
INIT
button to turn on the
AC VOLTS (M)
voltage source.
5.
Rotate Control Knob until a voltage value slightly less than the expected pickup
value appears on the
AC VOLTS (M)
display.
3.
Using the arrow key, highlight the
AC VOLTS (AUX)
. Press the
AC AUX
button
to turn the
AC AUX
Volts on.
4.
Rotate Control Knob and increase
AUX
AC Voltage output to approximately the
same test voltage as the
V (M)
output. Note the phase angle displayed,
V (M)
lags V (AUX)
.
The relay may be closed at this point depending on the measured
phase angle displayed.
5.
Using the arrow key, highlight the phase angle displayed. Using the Control
Knob, rotate the phase angle to 300 degrees. The result will be a balanced open-
delta voltage.
6.
Using the arrow key, highlight
AC VOLTS (AUX)
. Using the Control Knob, adjust
the
AC AUX
Volts to the expected pickup value. Using the arrow key, highlight
the
AC VOLTS (M)
. Adjust the voltage for both the
AC VOLTS (M)
and
AC AUX
for a balanced pickup value. Record the pick up value.
