SP 1-Ex 19
Note:
The output signal of (0-20mA, 4-20mA or 0-5mA - according to the specification) can be adjusted at the range
from 85 up to 100% of the rated stroke stated on the actuator
′
s nameplate. At values less than 85% the value of
the output signal is reduced proportionally.
4.5 Adjustment of the Capacitive Transmitter CPT1/A (Fig.6)
The chapter describes adjustment of the capacitive transmitter to the specified parameters
(standard values of output signals) in case they are reset. The capacitive transmitter serves as a
position transmitter of electric actuators with unified output signal of 4÷20 mA in electric actuators
SP 1-Ex , or as a feedback of a position controller, or if required it functions also as a remote position
transmitter of electric actuators with unified output signal of 4÷20 mA in electric actuators SP 1-Ex
with controllers.
Note:
In case that reversed output signals are needed (in the position ”OPEN” minimum output signal) contact
personnel of service centres.
The capacitive transmitter CPT1/A is adjusted by the producer to the fixed operation stroke
according to the order and wired according to the wiring diagrams placed into the cover. Check the
power supply of the user after connecting to terminal of the terminal board before the transmitter is
electrically checked. Adjustment of the capacitive transmitter can be performed when the position
switches are adjusted. The adjustment is performed with the power supply of 230 V/50 Hz and
ambient temperature of 20
±
5°C.
The following versions of electric actuators with built capacitive transmitters can be specified :
A) The version without any power supply (2-wire version) for EA SP 1-Ex
B) The version with a power supply (2-wire version) for EA SP 1-Ex
C) The version CPT as a feedback to the position controller for EA SP 1-Ex with controllers
