HV Enable (IN0):
CAUTION: For HV on the electrode, install a normally closed switch or
relay contact** between pins 1&2. This switch or relay should open
automatically when the wireline stop switch is activated or be opened
manually by the system operator when the line stops. FAILURE TO DO SO
COULD RESULT IN A FIRE HAZARD If the HV remains ON in the electrode
when your line is stationary, the wire insulation in the electrode will
heat and there is a danger of combustion.
External Reset (IN1):
To reset the spark tester fault relay with an external switch, wire a
momentary switch** between pins 1&3. When these contacts close, the
fault relay will return to a normal state. The interval that the contacts
are closed must exceed 50 ms.
(3) 22 ga. stranded
conductors rated
250V, less than 10
meters in length,
contained in a
common insulating
sheath
*When connecting auxiliary equipment to dry relay contact pins 1, 2, 3,or 4, observe maximum ratings of
120VAC at 2 amps, 240VAC at 1 amp.
4 - Pin Terminal Block Connections
Watch Dog (OUT2):
Dry relay contact pins 1&2 will close when the test voltage is between
the VWDL (Voltage Watchdog Low Threshold) and the VWDH (Voltage
Watchdog High Threshold) values.
Bare Wire (OUT3):
To activate external lights, alarms or relays* when a Bare Wire type
fault occurs, wire them between dry relay contact pins 3 & 4. If the
output function is set LCH or RVF, the dry relay contacts will remain
closed until the RESET button is pressed or when pins 1&3 are closed by
remote switch or relay output function is set to NLC, the dry relay
contacts will return to normal state after the interval known as the
ABMS (Any Bare Wire Alarm Time) has elapsed.
(3) 22 ga. stranded
conductors rated
250V, less than 10
meters in length,
contained in a
common insulating
sheath
HV ON Indication (OUT0):
Dry relay contact pins 5&6 will close when the test voltage exceeds
500v. For an indication that HV is ON in the electrode, wire a lamp or
auxiliary device* here.

conductors rated
250V, less than 10
meters in length,
contained in a
common insulating
sheath
Process Control (OUT1):
To activate external lights, alarms or relays* when a fault occurs, wire
them between dry relay contact pins 9,8 & 7. If the output function is set
to LCH or RVF the dry relay contacts will remain closed until the RESET
button is pressed or when pins 1&3 are closed by remote switch or
relay. If the output function is set to NLC, the dry relay contacts will
return to normal state after the interval known as the AFMS (Any Fault
Alarm Time) has elapsed.
* When connecting auxiliary equipment to dry relay contact pins 5, 6, 7, 8 or 9, observe maximum ratings of
120VAC at 2 amps, 240VAC at 1 amp.
**Switches and relays connected to pins 1,2, & 3 should be suitable for 24V low current applications.
