Troubleshooting
CAUTION:
Troubleshooting is to be performed by qualified service personnel
only. Failure to follow the procedures in this manual may result in danger to
personnel and equipment damage.
Phantom Faults are being indicated.
1.
Lateral wire line vibration or water may be present. See “Installation” for
information on drying, centering and restraining the product in the electrode.
2.
The high voltage mounting plate may be contaminated with dirt or
conductive material. Clean the mounting plate or replace.
3.
Inspect proper grounding of inner conductor.
4.
If, after 1,2,& 3 have been corrected, you still experience false counting due
to a capacitive loading effect on your test product,
change the “FD
-
CON”
setting in the Configuration menu
from “NOR”
to “RED”.
Note that your spark
tester will no longer meet the BS Standard for sensitivity but will still meet
the NEMA Standard for sensitivity.
The Fault Count
Displays “E.EXI”
1.
There is no switch or relay contact between Pins 1 & 2 (GND and HV ENABLE).
Refer to the table in “Installation” labelled “Terminal Block Connections,”
under HV ENABLE.
The Fault Count Displays “E.CV0”
1.
The clear safety cover is open.
The Fault Count Displays “E.RVF”
1.
The voltage was removed due to the spark tester being in the remove voltage
on fault mode. To
clear this press the “R” button on the front panel
.
The Fault Count Displays “E.RVC”
1.
The voltage was removed by a command through either the RS-485 serial
interface or through the fieldbus port. The voltage will need to be re-enabled
through that port.
The Fault Count Displays “E.HVD”
1.
The high voltage will not turn on due to a possible hardware failure. Please
