IA Inlet Actuator

Manual for use and Maintenance

Thank You:

Thank you for purchasing a Munters IA Inlet Actuator. Munters equipment is designed to be the highest performing,
highest quality equipment you can buy. With the proper installation and maintenance it will provide many years
of service.

Description:

The IA0090/IA0250D motor gearbox is a maintenance-free, compact drive unit for accurately opening and
closing air inlet flaps, air valves and ventilation curtains in livestock houses and crop storage buildings.

The IA0090/IA0250D motor gearbox features a self-braking worm gear transmission. This transmission ensures
that the drive shaft is not rotatable when the drive unit is stopped. The combination of carefully matched pinion and
worm reductions results in a quiet mechanical transmission.

The IA0090/IA0250D motor gearboxes feature a power switching integrated linear limit switch system with duty
and safety switches with an excellent switching precision of the end positions. The maximum switching range of the
limit switch system equates to 55 revolutions of the drive shaft. With use of an optional potentiometer built-in set, it
is possible to precisely feedback intermediate and end positions to a (climate) computer.

The IA0090/IA0250D motor gearboxes are finished with a blue powder coating and are supplied including
mounting bolts and spring washers.

IA0090 motor gearboxes: IA0250D motor gearboxes:

• Drive torques of 1000 lb.-in.; • Drive torques of 3540 lb.-in.;

• 1.2 at 60 Hz mains frequency; • 1.2 at 60 Hz mains frequency;

Suitable for intermittent use, duty class 3-30%, duty cycle maximum 25 minutes;
Provided with a two-sided output drive shaft for mounting one winch or belt drum or two 16-tooth

1/2”x5/16” zinc-plated sprockets for chain couplings;

• Manual drive enabled by means of a hexagon socket in electric motor shaft;

• Electric motors are standard tropic-proof and conform to protection class IP55;

• Available as 1-phase 115 V (60 Hz) electric motor with UL and CSA approval.

3.4 Rotational Directions and End Positions IA0090 Motor Gearbox

The rotational direction for the IA0090 is Clockwise [CW] (A) which is towards the motor and Counter
Clockwise [CCW] (B) which is away from the motor. Also visible are the corresponding limit switches for setting
the end positions A and B. See figure below.

Based on where the IA0090 and inlets are mounted and the direction the belt is wrapped on the drum,
determine which direction will be open and which will be close.

3.5 Wiring Diagrams IA0090 Motor Gearbox

Two wiring diagrams are applicable during installing and setting of the IA0090 gearbox. A temporary and a

permanent diagram are used in a number of steps according to Step 3.5.

Temporary connections (diagram 3.5.2):

This is only used for setting switch, according to Step 3.6, prior to making the permanent connections of the

IA0090 gearbox. Therefor a Temporary Power Cable is connected to the switch.

Permanent connections (diagram 3.5.4):

Make the permanent connections of the IA0090 gearbox after setting of the switch.

TIP: If the operation of position feedback is applicable, installation and setting of a potentiometer (P) is done separately in

Step 3.7 and Step 3.8.

!

CAUTION

The IA0090 motor gearbox is standard delivered with switch S1 in stop position. Switch S1
is still in STOP position when starting temporary or permanent connections!

rotation of the IA0090 if desired.
The direction of rotation can be
turned by changing connections
12 and 13 (L2 and L1) in the

Setting the Limits: See Image 3.6.1

1. Put switch (S1) into Stop position.

2. Apply power to the Clockwise [CW] (A) terminal 13.

3. Find the Allen Wrench that ships with the actuator.

4. Loosen the (2) Set Screws on each Adjusting Ring, at each end of the threaded shaft.

Setting the Clockwise [CW] (A) limit:

1. Put switch (S1) into CW (auto) position.

2. When end position [CW] (A) is reached put switch (S1) back to Stop.

3. On the [CW] (A) end, turn the Textured Brass Nut hand tight against the stop.

4. Now turn the Adjusting Ring over the Textured Brass Nut so far, that the working switch is just connected by the long

Adjusting Screw.

5. Now tighten the Set Screws firmly on the Textured Brass Nut. The Adjusting Ring cannot turn on the Brass Nut anymore.

Image 3.6.2

Setting the Counter Clockwise [CCW] (B) limit:

1. Put switch (S1) into CCW position.

2. When end position [CCW] (B) is reached put switch (S1) back to Stop.

3. On the [CCW] (B) end, turn the Textured Brass Nut hand tight against the stop.

4. Now turn the Adjusting Ring over the Textured Brass Nut so far, that the working switch is just contacted by the long Adjusting

Screw.

5. Now tighten the Set Screws firmly on the Textured Brass Nut. The Adjusting Ring cannot turn on the Brass Nut anymore.

The Limits are now set.

Connection and OperationsChapter 3

ATTENTION:

If the motor gearbox is manual operated by means of the hexagon socket in the electric motor shaft, with an limit switch
system which is set, it has to be checked that the end positions of the system will not be exceeded.
This can cause damage to the limit switch system, as a result of which the limit switch system will not function well
anymore.

Operating mode

Make sure the switch S1 is put in CW (A)/Auto position when permanent connections are done and

setting of the Switch is finished.

Image 3.6.3

Place the limit switch cover①, with the gasket ① still in place, and mount it with the four bolts.

See image 3.3.1.

TIP: If the feedback option is applicable, then first install and set the potentiometer (P) according to Step 3.4 and Step 3.5.

3.7 Potentiometer Installation Set: Installation

For an IA0090P, the Potentiometer set comes pre-installed in the
unit for a typical installation with a 1m belt we recommend using the
gears Z1 – 25 and Z2 – 25.

1. Slide Potentiometer with gear towards the other gear without

turning the shaft of the pot, so that the teeth on each gear nest
together and tighten the pot nut with the hex key wrench. See

Figure A.

2. The Potentiometer is pre-wired to the terminal bock K2. Make

the connections between the controller and terminal block K2. See Figure B. If the Pot is changing voltage from low
in the open position to high in the closed position then reverse the red and black wire on the controller side of terminal
block K2.

The Potentiometer installation is now complete.

For a 2m belt use gear ?? on the ??? shaft.

For a 3m belt use gear ?? on the ??? shaft.

3.8 Potentiometer table IA0090 motor gearbox (i=1,0)

The table below can be used to select the necessary gearwheels when fitting a potentiometer and
installation set in an IA0090 motor gearbox. The table shows the maximum number of revolutions of
the drive shaft of the IA0090 motor gearbox.

A range of 9 revolutions of the potentiometer has been chosen for maximum precision and sufficient
reserve rotations when using a potentiometer. If the desired number of revolutions falls below the
minimum value given, a 5-turn potentiometer may be used. In that case, the values in the table that
give the maximum number of revolutions of the drive, should be divided by 2.
