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 feedback 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:
Ø Input power: 115 Vac or 230 Vac, 50 or 60 Hz
Ø Input signals: 4-20 mA, 0-10 Vdc, 1-5 Vdc, or external command potentiometer
Ø Output signal: 4-20 mA
Ø Loss of command signal: fail in place, fail CCW, fail CW
Ø Speed Control: 1-19 times speed of actuator, independent timing for each direction
Ø Acting: direct acting (i.e. CW at 4 mA), reverse acting (i.e. CCW at 4 mA)
Ø Motor restart delay: Variable from one to thirty-two seconds
Ø Command sensitivity (deadband): Variable, range depends on command signal
Wiring
There are two terminal blocks on the controller board and two soldered wires. Terminal block TB1 is a 5
pole terminal block and is used for power terminations. Terminal block TB2 is a 9 pole terminal block and
is used for all control signals. The soldered red wire is the CCW circuit to the motor, while the soldered
black wire is the CW circuit to the motor. See wiring diagram under Figure WD1 below.

Setup and Operating Instructions
Jumpers
There are three jumpers on the controller board, JP1, JP2, and JP3 and two jumpers for the power terminal
block TB1. JP1 provides the option for 4-20 mA or 0-10 Vdc command signal input. JP2 is a sensitivity
jumper for the internal potentiometer. JP3 provides the option for 50 or 60 Hz input signal. The jumpers on
the power terminal block TB1 provide the option for 115 or 230 Vac supply voltage.

Calibration Potentiometer
There is one potentiometer designated for use in calibrating the Speed Control, Motor Restart Delay and
Sensitivity. Once the potentiometer position is stored in memory via the program pushbutton, it can be
moved without changing any of the settings. This allows one potentiometer to be used for multiple settings.

Output Indicators
There are three LEDs for visual reference during board operation. The red LED is lit as the controller
sends a signal to the motor to turn the actuator CCW or OPEN. The green LED is lit as the controller sends
a signal to the motor to turn the actuator CW or CLOSED. The yellow LED is a programming LED that is
lit each time a setting is saved in memory.
Push buttons
There are three push buttons on the controller board, PB1, PB2, and PB3. PB1 operates the actuator in the
CCW position when the controller is in the calibration mode. PB2 operates the actuator in the CW position
when the controller is in the calibration mode. PB3 is depressed each time a setting is required to be save
into memory.
Dip Switches
There are five dip switches which are used to calibrate the controller.
