2 Description

2.4 Controller access function

This function is a safety feature to safeguard the system against unauthorized manipulation.

Enter a PIN as desired to prevent unauthorized users from configuring the controller, changing

dispense applications, etc.

Enter number "2000" to unlock.

In locked condition, only the following functions can be accessed:

– On/off switching of product reservoir, i.e. reservoir pressurization/depressurization for

replacing the bottle of product..

– Start via foot switch, or by external actuation of a dispense cycle, not by

pressing key 13 Start.

– Resetting of error messages.

2.5 Modes of operation

2.5.1 Time controlled mode

Use this mode for internal timing of dispensing and delay times.

Times are adjusted by the user and remain unchanged for longer periods.

Benefits

– Very high precision of dispense timing is achieved.

– Maximum measuring accuracy for flow monitoring is available without constraints.

2.5.2 Continuous mode

Used when different dispense times are necessary, e. g. for different dispense amounts on the

parts, or for different parts.

Dispense times have to be provided by a higher ranking controller such as a plant PLC or a robot

controller.

Benefit

– High flexibility by synchronization with robot systems.

Limitations

– Fluctuations in PLC runtime directly affect both the dispense time and the runtime of the

connected advancing slides. Therefore, this mode is not recommended for options using

internally controlled advancing slides.

– Flow monitoring is available for time independent operation only.
