CAUTION Equipment Damage!
Actuators may be connected in parallel if not mechanically mounted
to the same shaft. Power consumption and input impedance must be
observed.
4
Position feedback cannot be used with Triac sink controller.
The actuator internal common reference is not compatible.
5
Control signal may be pulsed from either the Hot (source)
or the Common (sink) 24 VAC line.
8
Contact closures A & B also can be triacs.
A & B should both be closed for triac source and open for triac sink.
9
For triac sink the common connection from the actuator
must be connected to the hot connection of the controller.
Meets UL requirements without the need of an electrical ground
connection.
WARNING Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it may
be necessary to work with live electrical components. Have a qualified licensed
electrician or other individual who has been properly trained in handling live
electrical components perform these tasks. Failure to follow all electrical safety
precautions when exposed to live electrical components could result in death or
serious injury.

Note
Connect via safety isolation transformer.

Note
When several actuators are connected in parallel,
the maximum cable length must be divided by the
number of actuators.
Note
There are no special restrictions on installation if
the supply and data cable are routed separately.
