Control system
CONTROL UNIT
All the switches needed to operate the XR21S -equipment can be found on the control unit.
A movement (manual mode) or a series of movements (automatic mode) is selected in
the control unit.
Moving the control lever on the control unit enables movement or series of movements in
di󰀨erent directions.
The four digit display on the control unit gives information about faults, errors and di󰀨erent
phases of operation.
CONTROL SYSTEM LOGIC
The operations are controlled by a logic, which has been programmed into the control
system. An approach switch sends signals to the logic, giving it information about the
operational phases of the equipment.
The device can be either driven in automatic mode (A1 - A3), or in manual mode (A5),
one movement at a time.
If a fault occurs (e.g. approach switch malfunction), the device will stop in automatic mode.
In manual mode it will continue to run, except for the section causing the error. An error
code identies the cause of the interruption.
The error can be reset by turning o󰀨 the power (ignition key) and having another go.
