INSTALLATION
When Installing This Product…
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condi-
tion.
2. Check the ratings and description given in this specifi-
cation to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service techni-
cian.
4. After installation is complete, check out product opera-
tion as provided in these instructions.
CAUTION
Disconnect power before installation to prevent
electrical shock or equipment damage.
IMPORTANT:
For ease of adjustment, make all stroke and auxiliary
switch adjustments before installing the interface
module. After installation, access to the stroke adjust
cams and auxiliary switches inside the motor is
restricted. For complete details on performing these
adjustments, refer to the specification sheet packed
with the Modutrol Motor.
Installing Terminal Block
CAUTION
When installing the terminal block on the motor
quick connects, push the board straight down.
Rocking or tilting of the board can damage the
electrical connectors and result in an inoperative
wiring module.
1. Disconnect power from the M91XX Modutrol IV Motor to
prevent electrical shock or equipment damage.
2. Remove wiring box cover from the motor by removing
four screws.
3. Disconnect all field wiring from the motor.
4. If motor has an internal transformer, make sure trans-
former is not powered and disconnect secondary wires
from T1 and T2 terminals. Clip quick-connect termina-
tions from transformer secondary (brown) wires. Trim
1/8 to 1/4 in. (3 to 6 mm) of insulation from the ends of
the wire. Tin wire ends with solder.
5. Plug terminal block onto quick-connect terminals inside
wiring box.
6. Connect field wiring to screw terminals on terminal
block. See Fig. 2, 4, and 8 for terminal designations.
Trim wire ends neatly and tin with solder.
7. Position circuit module and secure.
SETTINGS AND ADJUSTMENTS
Module Adjustments
Q7130A Adjustments (Fig. 2)
The Q7130A provides selectable range, two-wire voltage
control (4-7, 6-9 or 10.5-13.5 Vdc). It includes a clockwise/
counterclockwise (cw/ccw) switch for replacing electrically
normally open or electrically normally closed motors. Remove
film on switch before use.
1. Select desired voltage range using the three-position
switch.
2. Select desired rotation. Select cw for electrically nor-
mally closed (motor drives clockwise , as viewed
from power end, to open with an increase in control sig-
nal). Select ccw for electrically normally open (motor
drives counterclockwise , as viewed from power
end, to close with an increase in control signal).
3. See Fig. 3 for typical system wiring.
4. Set controller to drive motor to fully open position and
then to fully closed position to check for proper opera-
tion. (See Table 2.)
