MICRONOR AG MR26 Current Loop Control Option 1 Product Description 1 1 Motor Pot Background Motorized Potentiometers are used in a variety of industrial automation and process control applications They are simple to use Easy to set up No computers required No software programs to write Easy to maintain Never obsolete The on board potentiometer s provide absolute positional feedback information or function as the variable resistor in an analog control or bridge circuit A motorized potentiometer provides a smooth uniform ramp throughout its timing cycle Rotary limit switches are programmed via the cams to electrically control events or provide status at pre set stages Applications include ramping up the field current of a DC motor or controlling the start up of a generator It can be very expensive to automate older control systems with manual controlled potentiometers rheostats or rotary cam switches Using commonly available 4 20mA loop control the MR26 offers a simple and inexpensive solution 1 2 MR267 Current Loop Control CLC Option The MR26 Current Loop Controller CLC option is designed to remotely control a Motorized Potentiometer a k a motor pot via 4 20mA current loop or via a remotely located 10k ohm potentiometer The motor controller will position the motor pot to any desired position within the mechanical range of the potentiometer 0 330 degrees for a single turn pot 10 turns for a ten turn pot

Due to the design of the cam switches can not be disengaged for more than 180 If the system requires that the switch does not make contact for more than 180 the normally closed contact must be wired As in Example A a system might require that the connection for a switch be made from 0 to 30 and there be no connection from 31 to 359 To accomplish this the switch must be wired in the normally closed position As in Example B a system that requires a connection for 315 the normally open contact must be wired so that a connection is made when the switch is engaged and no connection is made when the switch is disengaged The following instructions may be used to program the start and stop times of the switch Example A Example B Figure 7 Examples of Cam Programming and Switch Response Programming Using the PSN Key for NK4201 Double Cam and NK 4101 Single Cam Page 16 of 29 MICRONOR AG MR26 Current Loop Control Option e Step 1 Insert the key into unit as shown in the figure with the numbered side away from the cam and the notched side towards the cam e NKA201 NK4101 j M am Quo er ll N III id E Ki E 5 1 o Le pi d F 4 LM ig QH FIN ML ss J d Ai w 2 d E L R Step 2 While gently applying pressure against the cam with the key rotate the cam to e the desired position e Step3 For double cams NK 4201 adjust the other side of t
