NOTE: Vibration does not affect Modutrol IV Motor
performance (as it did in earlier Modutrol Motors).
When replacing a motor that was connected to an
R927C or R9107A Relay, Honeywell recommends
performing a retrofit to remove the relay and the old
motor. Replace both with one Series 90 Modutrol IV
motor (that is, do not replace the relay).

SETTINGS AND ADJUSTMENTS
Adjustable Stroke
On adjustable stroke motors, stroke is field-adjustable
between 90° and 160°.
• The mechanical adjustment (cams) establishes the fully
open (clockwise, as viewed from the power end) and fully
closed positions of the motor shaft.
• The electrical adjustment (trim potentiometer) matches the
feedback resistance change to the motor stroke.
• TRADELINE® motors are shipped with stroke set at 160°.
CAUTION
Careless Installation Hazard.
Use of excessive force while adjusting cams
damages the motor.
To avoid damaging motor end switches, set cams by
moving only the screwdriver top.
CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Never turn the motor shaft by hand or with a wrench.
Forcibly turning the motor shaft damages the gear
train and stroke limit contacts.
Before Setting Stroke
1.
Remove the top cover from the motor.
2.
Disconnect the controller from the motor.
3.
For models with an internal transformer (line voltage
motors), ensure that power (and nothing else) remains
connected to the motor.
IMPORTANT
Detach linkage from motor before adjusting stroke.
