to the free wheel. There must be a small play between the wheel A
(or wheel B)
and the driving wheel, so that
the transmitter shaft is not stressed in the direction perpendicular to its axis. Then correctly tighten the mounting bolts
of the transmitter bracket and secure with varnish.
The gear level of the wheel K3 and wheels A/B is chosen according to the table at the Figure 8. When the required
working stroke overlaps two zones it is better to choose the lower one.
Upon setting the suitable gear adjust the current transmitter according to the following procedure:
Attention!
Do not connect the CPT 1AAE transmitter without having checked the supply voltage. Transmitter outlets must not be
connected in the actuator with actuator ground conductor or earthed, not even incidentally.
1. Prior to checking feeding voltage, first disconnect transmitter from power supply source. On actuator’s terminals,
where the transmitter is connected to, determine voltage firstly using voltmeter with input resistance at least 1 M
Ω
.
Voltage must lie between 18 to 25 V, and must in no case exceed 30 V
(this would result in transmitter destruction).
Then, connect the transmitter so that the source positive pole is connected to the positive pole of the transmitter, i.e.
to the red/black conductor
(+)
– it is connected to the terminal 51 or the tip 41 for the version with a connector.
The negative pole of the transmitter
(black conductor)
is connected to the terminal 52 or the tip 42 for the version
with a connector.
2. Connect mA-meter, digital as far as possible, with an accuracy of at least 0.5 %, in series with the transmitter. Adjust
output shaft to
“closed"
position. While doing so, the signal value must drop. If this is not the case, turn the output shaft in
“closing”
direction until the signal starts decreasing and until the output shaft reaches
“closed"
position.
