Operating modes and functions:
External mode:
The signals from the valve input connector are looped through to the valve output connector. The signals
are measured internally and displayed. A setpoint specification is not possible.
Simulator mode:
The setpoint is generated internally and output to the valve output connector.
Depending on the preselection, setpoint can be set via potentiometer or touch screen.
The output setpoint and the actual value from the valve are measured and displayed.
Burden resistance at mA ranges:
In external mode, the current for actual value flows over the burden resistance of the ext. control.
In simulator mode over the internal burden resistance of the test device.
Dead man´s handle: Deadman activ
When working on systems, this operating mode is required.
A setpoint specification is only possible, when the button is pressed.
If the button released, the setpoint goes to 0%; The switching valves are not switched off, when the button is
released.
When the button is pressed again, the setpoint remains at 0%; A setpoint must be specified again.
The status of the dead man´s handle is displayed at the 'Range bar' (red / green)
External mode is activ
Simulator mode activ
Only use the operating mode "simulator mode" if the valve, which is going to get tested, has
been removed (disconnected from the machine) or if appropriate safety measures have been
implemented by the operator!
The dead man´s handle is not a safety device in sense of machine safety rules!
