(2) The right field (Menu) permits access to the Wheel Shuttle
®
with a tool (e.g. a screwdriver)
for parametrizing the controller. With this Wheel Shuttle, you can start the parametrization
and set the individual values.
(3) The left button (OK/Info) is used in normal operation to call up the stored parameters
“Enclosure Pressure“,“Purge Time“,“Function of Relay 3“,“Function of Relay 4“,“Switchpoint
of Purge Start“,“Switchpoint of Minimum Pressure“,“Switchpoint of Overpressure“ and
“Regulation“. During the parametrization, this button is used to select and confirm the
various parameters.
In the lower part of the cover, the terminal assignment of the Controller is shown. Terminals 1 to 3
are inputs; they provide electrical power to the Controller. Terminals 4 to 19 are outputs, over
which the monitoring unit drives its peripherals, e.g. the digital/ proportional controller.
Before switching on, ensure that the operating voltage of Control unit and
purge valve are equal to the voltage you want to connect
The operating voltage of the units shall only lie within the limits specified in
the technical documentation under Technical Data.
E.L.B. Ex-Geräte Bachmann GmbH is not liable for any subsequent damage.
Immediately after the compressed air supply is opened and the main voltage is applied, the
internal self-check of the controller begins automatically. Any fault occurring during the self-check
sequence is indicated by
An explanation of the fault numbers (XX) is given in Section 3.5 “Faults and Troubleshooting“,
Table 1: Faults detected during the self-check. If the self check is carried out successfully, the
initial purge of the enclosure commences, ending when at least five times the enclosure volume
has been circulated. The purge process is indicated by the message
in the display. All the time, the remaining purge time is counted down to 00 mins and 00 seconds.
Before switching on the electrical units in the enclosure, purge it out with a
quantity of protective gas corresponding to at least five times the enclosure
volume.
