GSP Error Codes
The "GSP" control has built in safety logic that reduces the risk of injury, damage and faulty
operation. When the “GSP” control recognizes a potential problem, its LED’s display an error code
and the unit will not allow any motor output until the fault has been cleared and the control has been
reset (placing the Forward/Neutral/Reverse switch in the Neutral position, or depending on the
circumstances, powering down & waiting 10 seconds before powering back up). The Error Table
on the following page lists the possible errors and their displayed error codes.

Reason for Error
Er.1 The “GSP” control was set to run when; electrical power was initially supplied to the control
(powered-up); or upon exiting either the Program Variable or Motor Control Variable settings.
To prevent unexpected motion generated from the “GSP” control, the motor output is
disabled and the error code displayed until the control is placed in “Neutral” to reset the error.
Er.2 Not applicable to this version of the control.
Er.3 The current draw of the motor exceeded the amperage set by the “Current Limit” variable of
the “GSP” control. Rectify the fault causing the excessive current draw, or increase the value
of the “Current Limit” variable - only if it is set too low. Then reset the “GSP” control by
either powering-down the control, or by placing the Forward/Neutral/Reverse switch in the
Neutral position to clear the error.
Er.4 As port “CN13” is usually used to interface normally closed travel limit switches, a closed
circuit between pins 1 and 2 indicate a non-activated reverse travel limit switch and a closed
circuit between pins 1 and 4 indicate a non-activated forward travel limit switch (a third limit
switch is sometimes connected between pins 1 and 3). Each time the “GSP” control is
powered-up, it checks the status of pins 2 & 4 of “CN13” with respect to pin 1 and if at least
one is closed circuit, the control will continue to monitor their status (as well as the status of
pin 3 where relevant) with respect to pin 1 (if both pins 2 & 4 were open circuit to pin 1 on
power-up, the control ignores all signals for port “CN13”). Once the “GSP” control has
recognized limit switches were connected to “CN13” but are no longer connected (i.e. pin 1 is
no longer in a closed circuit with either pin 2 or 4), the motor output is disabled and the error
code displayed. Rectifying the fault and resetting the “GSP” control by placing the
Forward/Neutral/Reverse switch in the Neutral position will clear the error. Note: turning the
power to the “GSP” control off, waiting ten (10) seconds then re-applying the power
will clear the error, but if the circuit remains open between pin 1 & 2 as well as pin 1 &
4, all signals coming into “CN13” will be ignored (failing to recognize limit switch
signals).
Er.5 Not applicable to this version of the control.
Er.6 When the GSP control recognizes that an encoder is connected, it expects to see encoder
signals within two (2) seconds of energizing the motor output. If no encoder pulses are
received within that time, the control will de-energize the motor output and display this error
code. Rectifying the fault and resetting the “GSP” control by placing the
Forward/Neutral/Reverse switch in the Neutral position will clear the error.
