180 degree operation. Enables selection of internal or external vacuum source. Turn
towards external vacuum source connection port to enable external source.
7. Incoming Air
Connection for main air supply. Max 10 bar clean dry non lubricated.
8. Mains Isolator
Isolates all incoming electrical supply.
Zones 1-5 contain electrical supply connector with thermocouple input connector. Additional
thermocouple and panel connector are provided for data acquisition purposes.
2.4 General Notes
Machines with heating options.
The control cabinet is cooled by a fan which runs whenever the main isolator is on. The
Mains isolator should be locked off and the supply to the panel disconnected if any work is
carried out within the panel or on the Hypaject heater zones.
The control panel should always be kept locked. The overall condition of the panel, heaters
and heater cables should be checked periodically for damage. Any damage should be
rectified immediately.
Temperature Controllers
The temperature controllers are pre-set before shipment. To adjust settings, please follow
the enclosed temperature controller manual. (See appendix A)
Over-temperature cut-out
If the temperature of any heating zone reaches the over-temperature level the over-
temperature cut-out will operate for that zone which illuminates the relevant red indicator on
the panel disabling output to the heater. The alarm state will indicate until the temperature
has fallen below the over-temperature level. The alarm must be reset by pressing the
appropriate reset button.
Thermocouple break
If a control thermocouple breaks or is disconnected for any zone the temperature controllers
will display ' - - -' and the relevant red fault indicator and cut-out circuit is activated as
indicated above.
Control fuse failure
Each Zone contains a separate control fuse. If any individual temperature controller fails to
operate, then the control fuse must be checked.
Lamp/cut out test
The circuits should be regularly tested. Operate each test button in turn. These test the
fuse failure and over-temperature lamps. With the panel isolator on, press each test button
in turn. The red over-temperature lamps will illuminate. Press the appropriate reset button
to reset
Earth connections
For safety reasons this machine must be earthed to a suitable earthing point.
