Introduction
Automax 'E' series electric actuators are rotary
valve actuators with output torques of 1500 and
3500 in-lbs. Various options are available including
a 4-20mA card for modulating.
Maintenance
All ports should be plugged to prevent debris and
water from entering unit. Ideally the heater and
thermostat option should be used to keep unit dry
during storage (if electrical hook-up is available) and
operation. Gear train is factory packed for
permanent lubrication. There is no need to change
the grease, however, should it become necessary to
refill, use a multi-purpose grease such as Du Bois
MPG-2.
Installation
Installation instructions apply to on-off units. See
IOM B00012 for instructions on modulating units.
1. Manually open and close valve to insure freeness
of operation.
2. Be sure valve and actuator rotate in the same
direction and are in the same position (i.e., valve
closed/actuator closed). If not sure, electrically
operate the actuator to determine its operating
range. The actuators are factory set and
calibrated for 90
°
operation; standard.
3. Mount actuator to valve with preferred Automax
AutoBrakit kit to assure proper alignment. DO
NOT use the manual override to align actuator
shaft to valve shaft, as this could drive the
actuator out of its operating range. Note: The
keyway supplied with the actuator for adaptation
is attached to the output shaft. Some valves
have manual stops; remove if appropriate or set
actuator to operate within the travel stop range.
4. Care should be taken to properly align valve
stem and Automax actuator output shaft.
Misalignment will cause premature failure of
assembly. Tighten all mounting hardware to
prevent damage or injury prior to operating
assembly for testing or use.

5. To connect power to terminal strip of actuator
you must first remove the actuator cover. Locate
schematic for proper terminal wiring.
6. Connect power to terminal strip according to
schematic diagram. Power should be fused with
a 5-amp slow-blow fuse. The actuator should be
wired and grounded per local codes.
7. Before replacing cover, actuate valve and check
to see if it opens and closes to preferred
positions. If valve does not, adjust cams to
properly set actuator travel.
8. Drive actuator to the desired open position. The
cams are adjusted in two ways. Simply depress
the splined "Quick-Set" cam against the spring
and rotate to desired location. Or, for very
precise applications, turn the screw inside the
cam to move the leaf into the micro switch.
9. To adjust close position, repeat step 8 with
actuator in the desired closed position.
10. Switch/Cam adjustment may be "fine-tuned" by
loosening switch bracket and moving switch
assembly in or out as necessary.
11. Operate the unit several times and ensure
operation. If unit is still out of adjustment, reset
cams and repeat from 8 until desired results are
reached.
12. Replace gasket and secure lid.
Caution: Actuator cover should be securely attached
before operating manual override. Disconnect power,
remove nut (if applicable) and rotate shaft/hand
wheel slowly. DO NOT FORCE. If unit jams or binds,
rotate the manual override in the opposite
direction. Rotate manual override clockwise to turn
output shaft clockwise as viewed from the top
of the actuator.
