feedback calibrated for full output shaft travel unless
otherwise specified at time of order. Feedback
signal calibration is necessary to ensure that the
signal current or voltage correctly corresponds to
the actuator output shaft position.
CHANGING FEEDBACK SIGNAL TYPE
The feedback signal may be specified as 4-20
milliamps or 1-5 volts when ordered or it may be
changed at installation, using the following methods.
FOR OPTION 7: To convert a 4-20 milliamp
configuration to 1-5 volts, remove the diode from
position R2 on the terminal board and replace
FEEDBACK SIGNAL OPTIONS
(OPTIONS 5 & 7 ONLY)
The feedback signal is an analog voltage or
current signal proportional to the position of the
drive’s output shaft. It may be used for remote
position indication or for automatic control
loop feedback. Actuators with Options 5 or 7
may be field connected to function as a two
wire transmitter or as a four wire active current
source. This circuit configuration is determined
by the position of Jumper Plug J5/J6 located
on the control board (J-J5 for 2-wire, J-J6 for
4-wire). See Figure 6 or 7 for J5/J6 location.
Unless otherwise specified at the time of order,
all Group 42 actuators are shipped with the
feedback circuit configured as a 4-wire system.
Also, all Option 7 models are shipped with a
249 ohm resistor (R5) mounted between output
signal terminals 13 and 14. This resistor is used
to ensure proper operation of the control board
when the feedback signal is not connected to a
control room indicator. A summary of position
feedback options, output signal ranges and
control board and terminal board part numbers is
provided in TABLE 1, below.
