5.1 Inspection on receipt
Physically examine all items for damage that may have occurred during transit.
Check the contents against the packing note.
If any item has been damaged in transit, this must be reported to the carrier
and to the supplier immediately. Do not return damaged instruments to the
sender as the carrier will not then consider a claim. Save the packing with the
damaged article for inspection by the carrier.
5.2 Connections to the electrical supply
The a.c. supply cable has three cores. Connect the brown lead to live, blue to
neutral and green/yellow to earth. When connected to the electrical supply and
switched on the instruments will light.
Warning
At no time must any panels be removed when connected to the supply.
5.3 Heating up of the source
Caution
Ensure that there is free space around the source. Do not obstruct any
of the vents in the control section, they are needed to keep the controls
cool. When the source is operating at any temperatures above ambient,
the front plate and case will become hot.
The source can be operated at any temperature in the range ambient to 1200°C
(2200°F), however the recommended temperature range is 350°C to 1150°C
(650°F to 2100°F). Set the controller to the required value as follows:-
1) When first switched on, the controller goes through a self check procedure.
When this check is completed two displays will be visible.
Upper display
Actual element temperature
Lower display
Set point temperature
2) To modify the set point press, the ‘Up’ or ‘Down’ button until the required
value is obtained.
The source will be ready for use at 1100°C/2000°F approximately 20
minutes after switch on.
The output light ‘OP’ indicates the state of the controllers output signal
to the solid state relay which in turn switches the power to the heating
element.
Note
All other controller parameters are factory set and locked. It should not
be necessary to adjust them.
