C1415-04/09: This manual provides installation and operating information for the Bettis
Controller Board C1415. Should you have any questions about the controller that are not
covered under this manual, please contact an authorized Bettis Actuation Technologies
Center or Bettis Electric Division, 19200 Northwest Freeway Houston, Texas 77065,
United States +281 477 4100 (281) 477 2801.
1.1 Bettis C1415 DC Motor Controller Board
The Bettis C1415 DC Motor Controller board is an accurate, easy to use, multi-function
servo-board, intended for use with brush type motors. No calibration .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:
— Input power: 12 Vdc or 24 Vdc
— Input signals: 4-20 mA, 0-10 Vdc, 1-5 Vdc, or external command
— Output signal: 4-20 mA
— Loss of command signal: fail in place, fail CCW, fail CW
— Acting: direct acting (i.e. CW at 4 mA), reverse acting (i.e. CCW at 4 mA)
— Torque trip sensitivity: Variable, range dependent on actuator torque rating
— Motor restart delay: Variable from one to thirty-two seconds
— Command sensitivity (deadband): Variable, range depends on command
1.2 Wiring
There are four terminal blocks on the controller board, designated as TB1, TB2, TB3
and TB4. Terminal block TB1 is a 3 pole terminal block and is used for the (-) Vdc power
termination along with the external trip reset terminations. Terminal block TB2 is a 9 pole
terminal block and is used for all incoming and outgoing control signals. Terminal block
TB3 is a 5 pole terminal block and is used for limit switch terminations along with internal
trip indication output terminations. Terminal block TB4 is a 7 pole terminal block and is
used for the (+) Vdc power termination along with limit switch and motor terminations.

1.3 Jumpers
There are four jumpers on the controller board designated as JP1, JP2, JP3 and JP4. JP1
provides the option for a 4-20 mA or 0-10 Vdc command signal input. JP2 is a sensitivity
jumper for the board’s internal calculation. JP3 and JP4 provide the option for 12 Vdc or 24
Vdc voltage inputs. See below for jumper congurations.
