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;

Provided with a two-sided output drive shaft for mounting one winch or belt drum or two16-tooth

⁄8”x

⁄8” 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.

Please Note:

To achieve maximum performance and insure long life from your Munters product it is essential that it be installed

and maintained properly. Please read all instructions carefully before beginning installation.

Installation Instructions

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

Image 2.1

Mounting IA0250W: Mounting

Mount the mounting plate for wall assembly to the IA0250 as follows:

M10 bolt

*Please observe the following allowed mounting positions when installing the IA0250 Motor Gearbox

Use the M10 bolt and washer from the mounting kit to mount the plates to the gearbox.

After mounting of the motor gearbox (with oil lubricant) the upmost oil plug has to be

replaced by the oil breather supplied in the mounting kit. 50

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!

equivalent parts) are configured toprovide power

to L1 (13) of connection block K1!

ATTENTION:

TIP: Reverse the direction of

rotation of the IA0250 if desired.

The direction of rotation can be

turned by changing connections

12 and 13 (L2 and L1) in the

connection block K1.

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.

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.

QM1244r1

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.
