To Replace ML784 or ML984
1. The old ML784 or ML984 actuators cannot be used with
new ML7984 valve actuators in the same circuitry,
unless the old models are each powered by their own
transformer to prevent cross-talking.
2. The ML7984 is a direct replacement for all old ML784
UP
and ML984, except:
DOWN
a. When replacing the old reverse acting models, the
signal input wires to the new devices no longer need
to be reversed. Just follow the terminal polarity des-
ignations and DIP switch settings.
b. When replacing the old actuator which has an Elec-
tronic Series 90 "Supermod" controller - e.g.: T775,
W973, H775, or W7100 - the old interface resistor
must be removed. The ML7984 Series 4000 will work
directly with the controller without the external 240
ohm resistor.
c. When replacing the old ML784 (mA model) in multi-
UP
DOWN
ple-actuator installations, resistor(s) will be needed.
Use Resistor Kit (part no. 272822) and set DIP
switches accordingly. See Figures 17 and 18.
To Replace ML684A
M25502
1. The new ML6984 is a direct replacement for the old
ML684A in single actuator or parallel multiple actuators
hook-up. The old and new actuators can be mixed in the
same electrical circuit. For multiple actuators controlled
by a common controller in parallel, these actuators must
be wired so that they all travel in the same direction.
2. When replacing the ML684A1009 (80 lbf) with this new
ML6984 on the V5045 valve, the installed valve adaptor
(part no. 272629A) on the valve stem and actuator
assembly is still needed.
NOTE: The 272630D position feedback/auxiliary switch mod-
ule cannot be used with ML6984 3-wire installation.
The 272630D requires continuous power.
