4.4.3 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. This is to prevent connected
devices from interfering with the measurement.
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
electronics module will seriously damage the electronics module.
WARNING: Explosion Hazard
● In non-intrinsically safe installations, the terminal boxes may only be
opened if the system is disconnected from the power supply.
● In non-intrinsically safe installations, the cables may only be disconnected
if the system is disconnected from the power supply.
● The window cover 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, or the area is known to be non-hazardous.
NOTICE:
Incorrect cabling may cause failure of the FLOWSIC600. This will invalidate
warranty claims. The manufacturer assumes no liability for consequential
damage.
