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 IA0250 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 IA0250 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 IA0250 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 86 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 IA0250 motor gearboxes are finished with a blue powder coating and are supplied including mounting bolts
and spring washers.
IA0250 motor gearboxes:
Drive torques of 3540 lb.-in.;
• 1.2 at 60 Hz mains frequency;
Suitable for intermittent use, duty class s3-30%, duty cycle maximum 25 minutes;

2.1 Mounting the IA0250 Motor Gearbox.
Mount the IA0250 motor gearbox according to the following instructions:
Always use an allowed mounting position as shown in image 3.1.
When mounting the IA0250, ensure that the
motor cover remains accessible so you will
have no problems connecting, setting and
operating the IA0250
Attention:
!
Please ensure that the IA0250 is
mounted securely, so that the building
structure can sufficiently absorb the
forces applied.
CAUTION
!

3.4 Rotational Directions and End Positions IA0250 Motor Gearbox
The rotational direction for the IA0250S 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.
3.5 Wiring Diagrams IA0250 Motor Gearbox
Two wiring diagrams are applicable during installing and setting of the IA0250 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
IA0250 gearbox. Therefor a Temporary Power Cable is connected to the switch.
Permanent connections (diagram 3.5.4):
Make the permanent connections of the IA0250 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 IA0250 motor gearbox is standard delivered. Check that switch S1 is
still in STOP position when starting temporary or permanent connections!

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.
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
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.
ATTENTION:
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.
TIP: If the feedback option is applicable, then first install and set the potentiometer (P) according to Step 3.7 and Step 3.8.

3.7 Potentiometer Installation Set (AC1429):
For an IA0250SP, the Potentiometer set comes pre-installed in
the unit for a typical installation with a 1m belt we recommend
using the gears Z1 – 24 and Z2 – 15.
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.

3.8 Potentiometer table IA0250 motor gearbox (i=1.6)
The table below can be used to select the necessary gearwheels when fitting a potentiometer and
installation set in an IA0250 motor gearbox. The table shows the maximum number of revolutions of
the drive shaft of the IA0250 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.
