Connect the signal:
Locate the correct connection terminals as shown on the previous page, then connect your input
signal on pos. 1 and 2 as shown below. Feedback, if applicable is connected to position 4.

NOTE 1:
Usually, the actuators are
shipped for 4 .. 20mA signal input.
For 1 ..5 V signal input, remove 250 ohm
resistor R66.
The actuator 4..20 mA output is internally supplying
the signal current and can drive sufficient voltage for
any sensing resistor of up to 250 ohms.
The potential of the external GND after the sensing
resistor may not be more than +6VDC / -2 VDC away
from the power GND of the actuator.
This feedback signal output is only available in
HANBAY MCx-B-xxxAF model actuators.

NOTE 3:
DO NOT CONNECT pin 4
directly or through a multimeter only to
ground.
A sensing resistor of 50 ohms or more
needs to be present.
Not observing this warning will damage
the equipment.
NOTE 2:
Signal Gnd. is NOT
ISOLATED from Power Gnd. in all
MCx-B-xxxAB basic models.
If your signal Gnd. is different from
Power Gnd. use HANBAY MCx-B-xxxAI
or MCx-B-xxxAF model actuators.
