Checking the cable loops
Check the cable loops to verify that the cables are connected correctly. Proceed as follows:
b
Disconnect both ends of the cable of the loop to be tested. This is to prevent connected
devices from interfering with the measurement.
b
Test the entire cable loop between SPU and terminal device by measuring the loop
resistance.
b
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.
b
Reconnect all cables after the loop resistance test.
WARNING:
The test voltage applied would seriously damage the electronic module!
WARNING:
● In non-intrinsically safe installations, the Exe terminal boxes and connect/
disconnect cables must only be opened if the system is disconnected from
the power supply.
● The front cap (with display panel) must only be opened if the system is
disconnected from the power supply and only 10 minutes or more after the
system has been switched off.
● Incorrect cabling may cause failure of the FLOWSIC600. This will invalidate
warranty claims. The manufacturer assumes no liability for consequential
damage.
