Gullco KR-200-L - Manual (Page 27)

T-7
Note: CN1, CN11, CN12, CN14 & CN15 are Molex KK, or
equivalent, 0.1” [2.54mm] spaced series connectors/headers
CN1 – Flash Programming Port
Note:
Factory use only.
CN11 – Tach Feed Back Connection
Pin 1 - Common
Pin 2 – Signal
Pin 3 – Sensor detection & current source
CN12 - Auxiliary “Hold” (Stop) Port
Pin 1 - Common
Pin 2 – “Hold” (Stop) (digital input active LOW)
Pin 3 – Port active recognition
Note:
When the “GSP-1000” control is initially powered-up, it looks to see if pin 1 & 3 are in a closed
circuit, thereby indicating a device/signal using this port. If the control does not see pin 3 connected
to common, it assumes that nothing is connected to this port and will not look for the auxiliary “Hold”
(stop) signal. Therefore, any auxiliary “Hold” (stop) device that is connected to the control
after it has been powered-up will be ignored. After the microprocessor has recognised that a
device is connected to this port, it will activate the “Hold” (stop) command when pin 1 & 2 are in a
closed circuit.
CN14 – Remote Speed Port
Pin 1 - Common
Pin 2 – 0 to 2.5 Kohm signal
Note:
The external resistance applied across pins 1 & 2 will regulate the motor speed up to the setting of
the Speed adjustment potentiometer on the “GSP-1000” faceplate (not necessarily 0 to 100%).
CN15 – Remote Direction Port
Pin 1 - Common
Pin 2 - Reverse travel direction (digital input active LOW)
Pin 3 - Forward travel direction (digital input active LOW)
Pin 4 - Spare (not used)
Note:
By connecting Pin 1 with either pins 2 or 3 (closing the circuit) the Reverse or Forward commands
will be activated. Avoid calling up Forward and Reverse simultaneously. The Hold (stop) command
has precedence over the Forward or Reverse commands. If either of these remote directions are
opposite to that of the Forward/Neutral/Reverse switch located on the “GSP-1000” control, the
motor output will be disallowed until the conflict is resolved.
