Resistance transmitted and position indicator setting
To set the position indicator proceed as follows: With the output shaft in the “closed” position slide out the gate 51
(Figure 8) by pressing it towards the transmitter, disengaging it from the pinion 49 (Figure 5). Then, turn the gate clockwise
to the stop which forms a column under the signalling unit. Then, re-engage the gate with the pinion 49. The transmitter
pointer should point to 0°. If it does not, move the gate 51 back before its stop and depress the gate 55. This will release
the transmitter pinion and the transmitter pointer can be set near the mark 0° on the transmitter scale so that their teeth
engage properly with each other, once the gate 55 gets engaged with the pinion. Carefully turn the transmitter shaft to
make sure their clinching is correct. Then, we can again slide out the gate 51 from engagement, pushing it more vigorously
towards the stop
(with the transmitter pointer moved to the mark 0° the pinion will slide through). Then, re-engage the gate
51 with the pinion 49. In this position, the oval openings in the toothed gates go parallel with the oval opening in the main
control board 67
(Figure 2). Now the transmitter is adjusted for the “closed” position. Then, loosen the screw 64 (Figure 8),
position the shifting lever 65 towards the transmitter to the stop point and retighten the screw 64.
Re-set the actuator to the “open” position; the transmitter pointer is re-set to a position between 0° and 160°. Release
screw 64 and turn aligning lever 65 anticlockwise until the transmitter indicator reaches 160°C sign. Subsequently re-
tighten screw 64 again and drop quick-drying ink on it to prevent it from releasing. Thus the transmitter is set to
“open”
position. The position indicator is mounted on the resistance transmitter axis 42 (Figure 8) with the screw 41. This screw
will be loosened in its “open” position, and the indicator is turned, so that the mark 100 on the indicator scale 40 would
coincide with the color dot on the view port in the control box lid. Subsequently, tighten screw 41 and secure it in
tightened position by dropping quick-drying varnish on it.
II. Vishay resistance transmitter
Alternatively, actuators MOA can be equipped with a Vishay resistance transmitter. This transmitter has a shaft
led out on one side, with double wheel 73, consisting of toothed gears A and B, fixed on the end of the shaft. The
principle of drive and adjustment of Vishay transmitter is identical to current transmitter CPT 1AAE. The only
difference consists in sizes of toothed gears A and B of double wheel 73, and thus also in table including values
for working stroke setting.
Setting of position resistive transmitter
First of all you must set the appropriate gear from the output shaft of the actuator to transmitter shaft according to the
required working stroke of the actuator shown in the following table.
Configuration is performed using the adjustable wheel K3 in the gearbox of the signal unit as per the previous
paragraph b). Further, you must bring the necessary gear of the double wheel, affixed on the transmitter shaft, into
meshing position. The wheel with the smaller diameter is marked A, the larger wheel is marked B.
The adjustment is made by moving the spacers 72 either under the transmitter bracket (wheel A is engaged) or above
the transmitter bracket (wheel B is engaged). This is done at the position where the transmitter bracket is the most
distanced from the gearbox.
