SP 0.1, SPR 0.1
While checking or adjusting the output signal of 4÷20 mA follow these steps:
•
Connect a mA meter of precision class 0,5 and loading resistance lower than 500
Ω
serially with
the transmitter (pole „-„; terminal 82)
•
Put the actuator to the position ”CLOSED”, the signal value should decrease.
•
Check the signal value for the position ”CLOSED” (4 mA).
•
Tune the signal with loosening the fixing screws (15) and turning the trimmer (10) until the required
value of 4 mA is reached. Tighten the fixing screws.
•
Put the actuator to the position ”OPEN”, the signal value should raise.
•
Check the signal value for the position ”OPEN” (20 mA).
•
Tune the signal with turning the trimmer (20) until the required value of
20 mA is reached.
•
Check the signal value for the position ”CLOSED” and then for the
position ”OPEN”.
•
Repeat the procedure until the change from 4 to 20 mA is reached with
deviation less then 0,5 %.
•
Disconnect the meter and lock the screws with a varnish.
B.) Adjustment of the Capacitive Transmitter with the Power Supply
1.) Check the power supply: 230 V AC
±
10% on the terminals 78,79
2.) While checking or adjusting the output signal of 4÷20 mA follow these steps:
•
Connect a mA meter of precision class 0,5 and loading resistance lower than 500
Ω
on the
terminals 81, 82.
•
Follow the procedure described in the previous chapter A.
C.) Adjustment of the Capacitive Transmitter Served as a Feedback of the Position Controller
While checking or adjusting the output signal of 4÷20 mA follow these steps:
•
Disconnect the circuit on the terminals 81 and 82 removing the jumper.
•
Connect power supply to the terminals 1 and 61.
•
Disconnect the control signal from the terminals 86 and 88.
•
Put the actuator to the direction ”
OPENING
” or ”
CLOSING
” with the handwheel or connecting power
supply to the terminals 1 and 200 for the direction ”
OPENING
”, or 1 and 24 for the direction ”
CLOSING
”.
•
Connect a mA meter of precision class 0,5 (e.g. digital) and loading resistance lower than 500
Ω
on the terminals 81,82.
•
Follow the procedure for the version without any power supply described in the previous chapter A.
•
Having the transmitter adjusted put the jumper again on the terminals 81 and 82 in case that the
output signal wont be used (the circuit through the terminals 81 and 82 should be closed).
•
Connect the control signal to the terminals 86 and 88
The user has to arrange grounding of the 2-wire circuit of the capacitive transmitter to the electrical
ground of a joined controller, computer, etc. The grounding should be performed only in one place in
any part of the circuit outside the electric actuator!
Note:
The trimmer (20) can be used to adjust the output signal of the capacitive transmitter to any value of operation
stroke in range from ca 40% up to 100% of the value of the operation stroke adjusted by the producer and stated
on the actuator
′
s nameplate.
3.6 Adjustment of pointer
After adjustment of the actuator and putting the
cover on it is needed to set the pointer. The pointer can
be set with turning of the pointer with a hand against the
mark (Fig.7) in the position "open" or "closed".
Note:
The end "open" and "closed" positions on the pointer
label are valid for nominal actuator angles (60 °, 90 °, 120 °,
360 °) in accordance with the type label of the actuator. In
