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 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 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 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 motor gearboxes are finished with a blue powder coating and are supplied including mounting bolts and spring washers. IA0090 motor gearboxes: Drive torques of 1000 lb. in.j 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 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. 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.

Chapter 3 Connection and Operations 3.4 Rotational Directions and End Positions IA0090 Motor Gearbox The rotational direction for the IA0090 is Clockwise [CW] (A) which is twords the motor and Counter Clockwise [CCW] (B) which is away from the motor. Also visable 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! S1 Stop!

CCW (Counter Clockwise) CW (Clockwise) GROUND NEUTRAL Image 3.5.3 Diagram 3.5.4 * Suitable for inductive load of 115V - 2,5 A IA0090 ATTENTION: When setting the Limit Switch after the permanent connections, make sure that S111 and P71 (or equivalent parts) are configured toprovide power to L1 (13) of connection block K1! TIP: Reverse the direction of rotation of the IA0090 if desired. The direction of rotation can be turned by changing connections 12 and 13 (L2 and L1) in the connection block K1. Munters Corporation, March 2017 QM1235r1 13
Chapter 3 Connection and Operations 3.6 Setting the Limit switch system Delivery: Make the connections from the controller to the actuator terminal block (K1) depending on which direction is Open and which is Close. See Image 3.5.3. Terminal Block (K1) Threaded Shaft End Position (B) End Position (A) Toggle Switch (S1) Image 3.6.1 Textured Brass Nut Set Screws in Adjusting Ring 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. Image 3.6.2 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. 14 QM1235r1 Munters Corporation, March 2017
Chapter 3 Connection and Operations 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. Place the limit switch cover1, with the gasket 2 still in place, and mount it with the four bolts. See image 3.3.1. Image 3.6.3 TIP: If the feedback option is applicable, then first install and set the potentiometer (P) according to Step 3.4 and Step 3.5. Munters Corporation, March 2017 QM1235r1 15
Chapter 3 Connection and Operations 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.

Chapter 3 Connection and Operations 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. IA0090 Munters Corporation, March 2017 QM1235r1 17
