MOUNTING
The actuator may only be mounted
beside or above the valve. Adjust the
valve in the right position before
mounting the actuator. (Fig. 3)
Before the actuator is fixed to the valve,
the adjustment cap must be removed.
Make sure that the actuator is in the
open position (factory supplied position)
before fixing the actuator to the valve
body. (Fig. 4)
The actuator must be mounted by hand.
Don't use tools or additional forces,
because actuator and valve may be
damaged.
CONNECTIONS
The electrical installation must comply
with the wiring diagram shown in Fig. 5
and Fig. 6.
LONMARK NETWORK INTERFACE
