● The GEMÜ 1435 ePos must be protected from direct impact
of rain water.
● Lay cables and and pipework so that condensate or rain
water that remains on the pipework / cables cannot enter
the cable glands of the M12 plugs of the GEMÜ 1435 ePos.
● Check that all cable glands of the M12 plug and the fi ttings
are mechanically secured.
● Check housing seal for correct position and damage each
time before closing.
● Close keypad cover properly immediately after use.
● Lock all covers (throttles, check valve) immediately after use.

2.4 Function
The GEMÜ 1435 ePos is an intelligent electro-pneumatic
positioner designed for mounting to pneumatic linear and
quarter turn actuators.
The positioner can be directly mounted to the actuator using
a suitable mounting kit. The mounting kit contains both the
mounting bracket / adapter and the appropriate travel sensor
with the relevant fastening screws.
Remote mounting is also possible, whereby the mounting
bracket / adapter is not needed.
The travel sensor measures the current position of the valve
and relays this position to the electronic control system of the
GEMÜ 1435 ePos which correlates the actual value of the
valve with the set value and adjusts the valve if necessary.
The information required can be called-up on the two-line
display of the GEMÜ 1435 ePos. Self-explanatory help texts
that explain the meaning of the parameters called-up are also
displayed.
The GEMÜ 1435 ePos is operated using four keys.
2.5 Fail safe function
The GEMÜ 1435 ePos has a fail safe function which ensures
that the outlets are vented during a pneumatic and electrical
power supply failure.
This fail safe function is not a substitute for specifi c plant safety
requirements. The GEMÜ 1435 ePos is not a safety control
system.
