BETTIS C1397 Controller Board Setup and Operating Instructions Bulletin 01597 11 01 This bulletin provides installation and operating information for the Bettis Controller Board C1397 Should you have any questions about the controller that are not covered under this bulletin please contact an authorized Bettis Valve Automation Center or Bettis Electric Division Mansfield Ohio U S A 419 529 4296 General Description The Bettis C1397 AC Motor Controller board is an accurate easy to use multi function servo board So easy the entire board can be set with a voltage supply a small screwdriver and one finger No equipment is required to set the board The basic concept of this controller is to read an external command signal and compare it to a feed back signal from a potentiometer linked to the output shaft When the signals are not equal the controller will energize either the clockwise or counterclockwise motor circuit This drives the actuator in the direction that reduces the signal difference Once the signals are equal the controller opens the motor circuit and the actuator is positioned properly awaiting the next external command signal change The controller has the following options Input power 115 Vac or 230 Vac 50 or 60 Hz Input signals 4 20 mA 0 10 Vdc 1 5 Vdc or external command potentiometer Output signal 4 20 mA Loss of command signal fail in place fail CCW fail CW Speed Control 1 19 times speed of

8. he run mode Loss of Command Signal Setting 4 20 mA or 1 5 Vdc operation only This command works only in the RUN mode i e when dip switch 1 is in the OFF position The board can be set to transfer to the CW limit or CCW limit upon loss of the command signal This is defined by dip switches 4 and 5 To move the actuator to the lowest setting i e 4 mA position upon loss of signal set both dip switches 4 and 5 to off To let the actuator fail in place upon signal loss set both dip switches 4 and 5 to on To move the actuator to the CCW limit upon loss of signal set dip switch 4 to on and dip switch 5 to off To move the actuator to the CW limit upon loss of signal set dip switch 4 to off and dip switch 5 to on Direct Reverse Acting This command works only in the RUN mode i e when dip switch 1 is in the OFF position Under normal or direct operation the actuator moves CW when the command signal is decreased and CCW when the command signal is increased This can be reversed by placing dip switch 3 to the on position Thus a 4mA or OVdc signal would move the actuator to the CCW end of travel Motor Restart Delay This delay can be used to smooth out or damp the response of the modulated device in a system that provides multiple command signals over a short period of time The delay can be set from 1 second factory setting to 32 seconds To change the delay perform the following steps in order 1

12. r the motor comes up to speed during each pulse Thus the movement of the motor at full load at a set time is shorter than if it was pulsing at no load The longer the on time is set for the more accurate the calculation will be Example lets say the speed reduction multiplier is set at 10 for a 30 second actuator which experiences full torque throughout the 90 of travel This would mean the calculated stroke time would be 5 minutes However due to the load there is a loss of 0 12 seconds in motor startup travel time With the on time set to 0 26 the motor has to start a minimum of 115 times With a loss of 0 12 second each start the total calculated loss would be 13 8 seconds so the actuator would have to run approximately twice as long to cover the whole range However with the on time set to 1 85 seconds the motor has to only start 16 times With a loss of 0 12 second each start the total calculated loss would be 1 92 seconds so the actuator would have to run only slightly longer to cover the whole range Bettis recommends that the on time initially be set to the highest setting Then ifthe stroke transition is too choppy reduce the on time setting to the acceptable level and adjust the speed reduction multiplier appropriately To set the on and off pulsing time perform the following steps in order To set the on time 1 Set dip switches 1 3 4 and 5 to the on position 2 Apply
