BAFFLE MACHINE AND CABLING WITHOUT HAND WINCH
Note:
When the baffle machine is connected directly to the
inlets, they will both travel at the same rate and the
normal load will be applied to the curtain machine.
Note:
When a Hand Winch is connected to the inlets and two free pulleys are connected
in line, the inlets will travel at the same rate as the baffle machine. For every 1” the
baffle machine travels the inlets will move 1”. The normal load will be applied to the
baffle machine.

BAFFLE MACHINE AND CABLING WITH HAND WINCH INSTALLED
Note:
When a Hand Winch is connected to the inlets and a Free Pulleys is connected
to the baffle machine, the inlets will travel at twice the rate of the baffle machine.
This is because for every 1” the baffle machine travels the inlets will move 2”.
Twice as much load will be applied to the baffle machine, therefore, it will have
half the pulling capacity.

When a Hand Winch is connected to the baffle machine and a Free Pulleys is

Only half of the load will be applied to the baffle machine, therefore, it will have

Electrical Wiring 4.
Step 1
All wiring should be in accordance with National, State and Local electrical codes.
Make electrical connections as shown on terminal block label inside actuator.
Step 2
Each actuator should have independent overload protection matched to its motor.
(Munters Circuit Breaker Catalog No. SY2010
Step 3
Open, Close and Neutral outputs from the air monitor control are to be wired to
Open, Close and Neutral inputs in actuator. See Figure 7.
Step 4
Turn on the electrical supply to the Actuator and the Air-Monitor Control. It is now
ready to operate.
WARNING
!
High Voltage, disconnect
power before servicing.

Adjust Close Limit Switch
Step 1
Loosen 2 screws in Close Limit Switch and slide switch back towards motor. Manually run Baffle Machine
to full close position for baffles or inlets. Slide Close Limit Switch against Guide Block so that it activates
Close Limit Switch and tighten screws. See Figure 9. Manually run Baffle Machine open about 1” and
back close to check for proper full close position.

Maintenance 6.
1) REMOVE DUST BUILDUP FROM BAFFLE MACHINE: Using a soft brush or dry
cloth. Never use liquids to clean electrical cords or wires.
2) GREASE BALL SCREW AND BEARING: A high quality Lithium based grease
should be applied to the ball screw, bearing and pulleys every 6 months
depending on the frequency of operation. Also, check to make sure that the
pulleys will turn freely.
3) CHECK CABLES: Confirm that all cables are in good condition and are properly
positioned in the groove of the pulleys. Check this regularly to avoid damage to
the building or equipment. Check any clamps being used to verify they are secure.
4) CHECK LIMIT SWITCHES: Verify that the limit switches are adjusted to allow the
air inlet to open and close within the inlets operating range. This should be per-
formed every 6 months.
5) CHECK ELECTRICAL CONNECTIONS: With the power turned off to the unit,
verify that the termination points are secure and all wires are in good condition.
This should be done yearly.
6) CHECK GEARMOTOR: No lubrication or adjustment is needed on the gearmotor.
Some maintenance may be necessary for reliable operation if the unit will sit idle
for an extended period of time. If the unit will sit idle for more than one month, the
following steps should be performed before actuator is put back into service.
Step 1 - Apply power to the actuator in the open and then the close direction.
Step 2 - Verify that the gearmotor will operate in both directions.
Step 3 - If the unit will not operate, refer to the Troubleshooting procedures for
further instructions.

In order to make these checks a voltmeter is required. All actuator circuitry is 120VAC. To troubleshoot, power must
be on. Use EXTREME CAUTION when checking voltage. DO NOT attempt these test if you are not experienced
in working on electrical control systems. Instead, contact a qualified electrician or service technician. Refer to the
following wiring diagrams while trouble shooting.
Figure 12: BA1701
Figure 13: BA1701-30
For BA1701*:
A. CLOSE:
1. Check for 120VAC at gray* and red wires on motor. If voltage is present, repair or replace motor
2. Check for 120VAC at #4 and #1(neutral). If voltage is present, replace limit switch.
3. Check for 120VAC at #3 and #1(neutral). If voltage is present, replace DPDT relay.
4. Check output of Actuator control to make sure the actuator is receiving a signal to close. If voltage is not
present, check main electrical service panel in building and wiring from control.
B. OPEN:
1. Check for 120VAC at blue* and red wires on motor. If voltage is present, repair or replace motor
2. Check for 120VAC at #9 and #1(neutral). If voltage is present, replace limit switch.
3. Check for 120VAC at #7 and #1(neutral). If voltage is present, replace DPDT relay.
4. Check output of Actuator control to make sure the actuator is receiving a signal to open. If voltage is not
present, check main electrical service panel in building and wiring from control.
WARNING
!
High Voltage, disconnect
power before servicing.
