The actuator may be mounted using either the 3/8 inch brass mounting
sleeve or by attachment using the clearance holes in the actuator body.
When using the brass mounting sleeve, the actuator may be mounted to a
wide variety of Newport components in one of four ways:
1. Unscrew the retaining nut and insert the 850G into the mount. Use
a spanner wrench included to tighten the nut.
2. If the mount has a clamping screw, the retaining nut is not used.
Simply insert the actuator and tighten the screw.
3. In the rare case, that neither of the above clamping methods can
be used, it might be necessary to partially disassemble the device
the actuator is being used in. When access to the retaining nut
side is reached, simply follow method No.1 above.
4. For mounting in panels up to
actuator and tighten retaining nut.
The 850G is equipped with a knob for manual coarse positioning (except
low speed versions, 850G-LS). Approximate position in both inches and
millimeters, can be read using the scales on the window and the scribe
mark on the lead-screw nut. A small amount of resistance should be felt
when turning the knob. This is a result of back driving the gearhead motor
assembly and is normal. Attempt to turn the knob smoothly, avoiding
abrupt starts and stops, to minimize the chance of damaging the motor
gearhead. Power to the motor must be off while executing a manual move
or damage may result to the gearhead. If excessive resistance is felt while
trying to turn the manual knob, check to verify motor power is off. If you
are still unsure, disconnect the actuator cable completely and compare
the turning resistance. It should be approximately the same as when the
cable is attached with the motor power off.
