Addressing SQM4 Actuators
Before actuators can be operated by the LMV5 they must be addressed and
the direction or rotation must be set if it was not previously set.
Depending on direction of rotation and home position set in the LMV5,
the actuator may rotate as soon as it is addressed. For this reason it is
highly recommended that the actuator shaft be uncoupled from the
valve / damper when the actuator is addressed.
Addressing is accomplished by going under Parameters & Display >
Actuators > Addressing and selecting the actuator to be addressed.
The AZL5 will then prompt the technician to press the red address button
on a specific actuator (air, gas, aux1, etc...). The red address button is
located under the plastic cover on the back of the actuator. After the red
address button is pressed on a specific actuator, the AZL5 should indicate
that the address assignment is successful.
The actuator's green LED should also blink a certain number of times after
the actuator has been addressed. One blink means air actuator, 2 = Gas or
Gas/Oil, 3 = Oil, 4 = Aux1, and so on. This is also outlined in the parameter
worksheet (Section 4-2). A solid (non-blinking) LED on the actuator means
that the actuator has power, but is not addressed.
Note: Actuator positions are stated in degrees (0 to 90
100%)
The addressing of any actuator can be erased (un-addressed) by holding down the red
button on that actuator for approximately 8-10 seconds, until a solid, non-blinking green
LED occurs. The actuator must be connected to power and CanBus to do this.
If an actuator is not addressed, and has power (12VAC1 and / or 12VAC2 connected) the
green LED will remain solid (non-blinking). Only 12 VAC (one wire) is necessary to light the
green LED, but 24 VAC is necessary (both wires) to have the actuator operate properly.
If an actuator has been addressed, and has correct power (12VAC1 and 12VAC2), but one
of the CanBus wires is disconnected, the LED will not light. The LED my blink for a couple
of seconds, but then will go blank if the CanBus wiring is not correct.
