Tandem Operation

The tandem configuration provides twice (with two actuators) or triple (with three
actuators) the running and spring return torque of a single actuator. The actuators may
be mounted in tandem using the Z-M9000-158 Tandem Mounting Kit. To mount a third
actuator, user-configured bracketing is required.
Follow these guidelines for tandem operation:
• Two or three actuators may be operated in tandem on the same shaft.
• Each actuator requires separate 24 volt power. When two or more actuators
connected in tandem share a common power source, the total maximum power draw
is actually 1.5 times the normal running current for each actuator.
(Total Power = Number of Actuators x Running Power x 1.5).
• Only one of the actuators can be configured as the master. Set the selector switch to
the master position (Figure 11 e 13).
• The other actuator(s) must be configured as slave(s), by setting the tandem selector
switch to the slave position (Figure 11). Only DMF1.x0S models can be used as a
slave.
• The master can accept DC 0-10 V or DC 2-10 V, or 4-20 mA command signals based
on the master's switch settings and/or external resistor.
• The master and slave(s) must have matching RA/DA settings.
• The master and slave(s) must spring return in the same direction.
• Once tandem-operating actuators are mounted to a damper shaft, manual override is
no longer an available function.
• Each slave actuator must have its tandem selector switch (Figure 11) set on the slave
setting. Its gray command wire must be connected the master's orange feedback wire.

Manual Override

Use only the supplied manual override crank to reposition the actuator hub when using
the manual override feature.
1. De-energize the actuator.
2. Insert the hex end of the manual override crank into the manual override adjustment
point on the face of the actuator.
3. Rotate the manual override crank in the direction indicated by the arrow on the label.
4. Rotate the manual override crank a half turn in the opposite direction to lock the
actuator hub in place.
5. To unlock the actuator hub, rotate the manual override crank in the direction indicated
by the arrow on the label. The actuator hub automatically unlocks when power is
applied to the actuator, and returns the actuator to normal drive and spring return
operation.
IMPORTANT: Applying excessive torque to the manual override or running the manual
override with a power tool may damage the internal components of the actuator and
cause premature failure. end of travel, the rotational resistance increases; do not force
the actuator hub past this point.
