Press ENTER to edit the Access Code
The Access Code enables access to the pump buttons and all menus.
The access code will have to be re-entered after 25 minutes of no operator activity. The system will then
automatically lock the use of the keys which control the ON/OFF and AUTOMATIC and MANUAL functions.
This is designed to protect the system from tampering.
Digital Input State M (Main Inputs)
Displayed is the state of the Digital inputs
X = energised
- = de-energised
See INPUTS for configurable options for this item.
Highest Pressure
Displayed is the state of the Digital outputs
X = energized
- = de-energized
See OUTPUTS for configurable options for this item.
PID Error
Displayed is the calculated error between the Set Point and actual pressure.
Curr & Max Retry
The number under “Curr” is the current number of times the main processor has
not been able to communicate with the analogue system. If it is not at Zero it indicates
that the analogue system has been subject to noise and may have had to restart itself.
If this display continuously cycles from incrementing to 20 and resetting to 0, it indicates a malfunction with the
analogue system (contact your dealer for advice).
The number under “Max Retry” is the maximum number of times the
main processor has not been able to communicate with
the analogue circuitry. If it is at 20 there may have been a disruption
in the analogue system and it was unable to restart itself. The main
processor has forced it to restart.
Temperature
Displayed is the current temperature in degrees C,
read from the temperature sensor on the circuit board.
Modbus Monitor
Used to monitor serial communication data transmit & receive transaction & errors.
