maximum signal is present on Y0, Y1, Y2, or Y3, then the actuator will modulate through
the full rotational range in response to a 4 to 12 mA signal applied at ZF. (Maximum
signal can be easily achieved by bridging terminals U4 and Y0.)
See Figure 16.
NOTE: It is possible to configure the actuator for split range operation 12 to 4 mA and
20 to 12 mA. Consult your authorized Siemens Building Technologies
combustion products sales representative for details.

SQM5x.xxxxxKx
Actuators
SQM5x.xxxxxGx actuators contain the AGA56.41A… circuit board with terminals Y- and
Y+ for 4-20 mA modulating input.
SQM5x.xxxxxHx actuators contain the AGA56.42A… circuit board with terminals Y, M
and U for 0-135 Ω modulating input.
SQM5x.xxxxxKx actuators contain the AGA56.43A… circuit board with terminals Y and
M for 0-10 Vdc modulating input.
Input Signals
The AGA56.4xA… circuit boards accept the following additional input signal:
Line voltage
• Power to A drives the actuator open to the setting of switch cam I (Maximum).
• Power to Z drives the actuator closed to the setting of switch cam II (Economy).
• Power to ZL drives the actuator closed to the setting of switch cam III
(Minimum).
Output Signals
The AGA56.4xA… circuit boards do not provide output signals. Install a double
potentiometer ASZ22…to obtain a 0-1000 Ω actuator position output signal.
