4.3 Adjustment of resistant transmitter (Fig.4)
The resistant transmitter is in the UP X.X used to function as a remote position indicator.
Before the resistant
transmitter adjustment the
position switches have to be
adjusted
(S3,S4). Adjustment
consists in setting of the resistance
in the defined limit position of the
EA.
Notes:
In case that the EA is unused within
the complete operating stroke
range following the angle selected
on the particular stroke line, the
“Open” limit position resistance
value will un-dergo proportional
reduction.
The transmitters are used with
resistance according to the
customer's specification. With EA
of 2- wire converter a transmitter
of 100
Ω
resistance is used .
To adjust the transmitter follow these steps:
•
Loosen
the
fixing screws (9) of the transmitter holder and push the transmitter out of mesh.
•
Put the
actuator
to the position ”closed” (with the handwheel, until the corresponding position switch S2 or
S4 switches).
•
Connect a meter for resistance measuring to the terminals 71 and 73. For the transmitter RP 19 rotate the
transmitter shaft (11) until resistance of
≤
5% of the nominal transmitter resistance can be read on the meter,
for the transmitter PL 240 the value shall be
≤
5% of the real transmitter resistance.
•
In the position put the transmitter to mesh with the drive wheel and fix the fixing screws on the transmitter
holder.
•
Please check the resistance value in both of the final positions and in case of need repeat the procedure.
Once the device is adjusted in a correct way disconnect the meter from the terminal.
