In case of returning the meters for inspection or repair to the COMAC CAL s.r.o. factory, enclose please the completed form, see the last page of this manual. Without having one, we will not be able to handle your requirement for modification or possibly repair your meter correctly and promptly.
After completion, close the unit and tighten all screw. Total depth of box is 200mm!!! Technical and installation manual FLOW 38 Batch (impulse) Page 5 (total 26) COMAC CAL s.r.o.
Similarly, fasten the wires for supply voltage and control outputs. At this stage the device is ready to operate. The internal control board is already connected with a measuring device – this has been done inside the COMAC CAL factory. If this is not desirable, do not interfere with the wiring. Technical and installation...
Meter wiring of sensor (Standardly for inductive sensor is made in COMAC CAL factory) Sensor cable connection using pulse output from flow meter sensor (not for inductive sensor): The sensor is connected via M12, 8-pin connector against the socket on the cover's body.
Wiring connection examples – passive impulse output: Terminals Due to CR≈100% and If = 2.5 mA it is advisable to choose the collector current up to 2.5 mA. Technical and installation manual FLOW 38 Batch (impulse) Page 8 (total 26) COMAC CAL s.r.o.
