OPERATION
Use Series 61 and 62 Modutrol IV Motors for standard Series
60 operation (drive open, hold, drive closed). Series 62
motors can also be used with the feedback potentiometer as
an input to the controller.
See Table 10 for details on motor response to controller
signals.
NOTE: Reverse the wires at either the motor or control-
ler.
To reverse the rotation direction of a non-spring return motor:
• Reverse the wires at terminals W and B.
Table 10. Modutrol IV Motor Operation.
CHECKOUT
After the installation and linkage adjustment, check the entire
motor and control hookup. Proper checkout ensures that:
• The motor operates the load (damper or valve) properly.
• The motor responds properly to the controller as the input
varies. See Table 10.
• The auxiliary switch, if used, operates at the desired point
of motor rotation.
1.
Inspect motor, linkage, and valve or damper to ensure
all mechanical connections are correct and secure.
NOTE: In damper installations, the pushrod should not
extend more than a few inches past the ball
joints.
2.
Ensure that there is adequate clearance for the linkage
throughout the entire motor stroke without binding or
striking other objects.
3.
Drive the motor fully open and fully closed. See Table
NOTE: Refer to controller or system instructions for
additional checkout procedures.
M62 Checkout
The following procedure will verify that the M62 external
feedback potentiometer is working for a -F or -S model.
• Connect 24 VAC to terminals 3 and 4.
• Connect 5-10 VDC to terminals Y and G (c
to Y and - to G).
• Connect either a voltmeter or an oscilloscope to
terminals T and G (c to T and - to G).
• Connect terminal R to terminal 1 to drive the motor
towards the fully closed position.
