4.1 Error Messages
InsulGard performs various tests at powering up, before every measurement and in
some more situations. In the case of a fault, an error message will be displayed and the
status relay contacts will open. The error message on IG display will appear as follows:
♦
--Sync--
- Loss of synchronization signal. Check the jumpers that are shown in the
Figure 6.1 at the Appendix 2 for internal synchronization. Check for synchronizing
external signal that should be above 0.4VAC and also refer to the Appendix 2 for correct
jumper’s configuration. Refer to Appendix 2 of this manual for more details.
♦
CLOCHErr
– This message indicates that some data in the device internal memory
has date stamp that is later then the current date. This destructs a consistency of data.
The appropriate action will be set correct date and time and delete all data that is later
then current time. (Refer to DATE setup from keypad).
♦
ErrorICH
– PD measuring channel did not pass calibration. If appears consistently,
the device must be repaired.
♦
ErrornCH
– PD noise channel did not pass calibration. If appears consistently, the
device must be repaired.
♦
FLASHErr
– the error reading from internal flash memory. May be fixed by deleting
data from device memory. If this does not help, the device must be repaired.
♦
STOPPEd
– Measurements are stopped and the device will never resume
measurements automatically. Use RESUME command from keypad or from PC.
4.2 Fuse Replacement
Attention!!! Fuse replacement requires partial disassembly of the device and
must be performed by a trained person. Contact your local Cutler-Hammer
representative for assistance.
If 120/230VAC power is present, but the device display does not light, the fuse then
possibly been blown. Fuse replacement may address the problem.
Attention!!! For 120 VAC Application use a 5x20 mm , 0.20 Amp, 250VAC . (We
recommend 195 Series by Wickmann, Digi-Key part number – WK5034-ND). For
230 volt applications use a 5x20 mm , 0.08 Amp, 250VAC . (We recommend 195
Series by Wickmann, Digi-Key part number – WK5026-ND).
Attention!!! If after fuse replacement the second fuse is blown up while powering
the device up, do not attempt replacing the fuse for the second time. Contact
Cutler-Hammer representative for device service.
Fuse location is shown on Figure 11 with the device protection cover taken off.
