Checking the cable loops
Check the cable loops to verify that the cables are connected correctly. Proceed as follows:
Disconnect both ends of the cable of the loop to be tested.
Test the entire cable loop between SPU and terminal device by measuring the loop
resistance.
If you want to test the insulation resistance as well, the cables
must
be disconnected
from the electronic module before using the insulation resistance tester.
Reconnect all cables after the loop resistance test.
WARNING:
Applying test voltage to the cables before disconnecting them from the elec-
tronics module will seriously damage the electronics and compromise the
intrinsic safety of the FLOWSIC60, respectively.
WARNING:
The front cap of the Signal Processing Unit (with display) may not be
opened. Opening results in nullification of Ex protection rating (see
label
). Repairs to the electronics with casting may only be carried
out by the manufacturer.
Incorrect cabling may cause failure of the FLOWSIC60 and compromise its
intrinsic safety. This will invalidate any warranty claims. The manufacturer
assumes no liability for consequential damage.
