3.2 Adjustment of position switches (version without position transmitter) (Fig.3)
While adjusting follow these steps:
•
Set the actuator to the end position "closed".
•
Loosen the nuts M1 and M2 locking the cams enough to have the Belleville spring creating the
pressure on them.
•
Turn the cam V4 counter-clockwisely until the switch S4 switches.
•
Reset the actuator by the operation angle (60°, 90°, 120° or 360°) to the end position "open".
•
If during resetting the actuator stops because of switching-off of the end switch S3 before the
required position, it is needed after loosening of the nuts M1 and M2 to turn the cam V3 counter-
clockwisely until the required end position "open" is set.
•
Turn the cam V3 clock-wisely until the switch S3 switches.
Set additional positional switches following these steps:
•
Set the actuator to the position required for switching of
the switch S6 in the direction "closing".
•
Turn the cam V6 counter-clockwisely until the switch S6
switches.
•
Set the actuator to the position where the switch S5 is to
switch in the direction "opening".
•
Turn the cam V5 clock-wisely until the switch S5
switches.
•
After adjustment of the position switches fix the cams
with nuts M1 and M2.
Note:
The position switches of the actuator with the position transmitter
can be set in connection with the range possibilities of the
transmitter.
3.3 Adjustment of resistant transmitter
The resistant transmitter is in the EA SP used to function as a remote position indicator; in the
EA SPR to function as a feedback in the position controller and if needed also in the position of a
remote resistant position indicator.
Before the resistant transmitter adjustment the position switches have to be adjusted.
The transmitter cannot be adjusted to another operating angle as stated on the nameplate of the
actuator.
Adjustment consists in setting of the resistance in the defined limit position of the EA.
Notes:
1. In case that the EA is not used in the whole stroke range given on the nameplate, the resistance in the limit
position "open" is proportionally reduced.
2. In the EA SPR 2000
Ω
resistant transmitters are used. In the other cases if the resistant branch is lead to the
terminal board the resistance of the transmitters is according to the customer's specification.
To adjust the transmitter follow these steps:
•
Loosen the fixing screws of the transmitter holder and push the transmitter out of mesh.
•
Connect a meter for resistance measuring to the terminals 71 and 73 of the EA SP terminal board,
or to the terminals 7 and 10 of the EA SPR terminal board.
•
Put the actuator to the position ”closed“ (with the handwheel, or with the local electric position
control until the corresponding position switch S4).
•
Rotate the transmitter shaft until resistance of
≤
5% of the nominal transmitter resistance can be
read on the meter in case of EA SP , and 3 up to 7% of the nominal transmitter resistance in case
of EA SPR, i.e. with the resistant transmitter with the converter PTK1.
•
In the position put the transmitter to mesh with the drive wheel and fix the fixing screws on the
transmitter holder.
•
Disconnect the meter from the terminal board.
