Model HF-15B High Frequency Spark Tester
HF-15B Instruction Manual – Page 29
Fault Reset (FR)
To reset the spark tester fault relay with an external switch or relay, 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.
Spark Tester Outputs
Output Functions are designed to relay information to an alarm, PLC, etc. The
Output functions can be assigned to output pins labeled ‘OUT 0, OUT 1, OUT 2,
and OUT 3.
General Outputs
Output Disabled (OFF)
This output will not do anything, under any condition.
Cover Open (CVO):
This output will change state when the safety interlock cover is open. If the
safety interlock cover is closed, the spark tester is able to produce high voltage.
Unit Malfunction (UER)
This output will change state when there is a hardware malfunction that could
cause the unit to operate outside of acceptable limits.
Voltage Monitor Output Options
High Voltage On Lamp (HVL)
This output will change state when the actual voltage is equal to or above the
set “HVON” configuration item value, and will turn off when the voltage is equal
to or below the set “HVOF” configuration item value.
– High Voltage On
Set in kV. If the actual voltage goes above this set point, any
“HVL” output will change state.
– High Voltage Off
