Setting up the controller

Before using the controller (or during its lifetime) certain parameters may have to be set, depending on specific
requirements. To do this the controller must be set to supervisor level (Level 2).

Set Point Ramp Rate

To control the rate at which the temperature rises to sepoint, the SP.RATE function is used.

Before setting the ramp rate, it is advisable to set the setpoint to a low value, preferably 0°C. Once the ramp rate

has been set the required setpoint can be entered from the home menu. Doing so will activate the ramp rate, which

working setpoint will be shown on the lower temperature display (This is the setpoint controlled by the ramp rate).

When the process temperature has reached the setpoint value at the given ramp rate, the run indicator will turn off

AFTER USE

When you have finished heating samples, remember that parts of the unit, inserts and associated accessories

may be very hot. Take the precautions listed earlier. We recommend that the inserts should be allowed to cool
to 100°C before being removed from the OMEGA CL1201 unit. They will still have to be handled with care.

INSERT BLOCK REMOVAL

If you need to remove an insert while it is hot, first remove the ceramic top insulator, then use the allen key
supplied to loosen the insert block and then screw the extractor tool into the threaded hole and lift the insert out
carefully.

Never leave the extractor tool in the insert while it is being used in the CL1201 unit.

The ceramic top insulator must be in place when operating the unit.

section. NOTE THAT THIS EQUIPMENT SHOULD ONLY BE DISMANTLED BY PROPERLY TRAINED

PERSONNEL.

GENERAL ADVICE/TROUBLESHOOTING

You can clean the case of the CL1201 with a cloth dipped in water or ethanol (methanol can also be used).
No part of the case or cover should be immersed in the solvents.

The OMEGA CL1201 should be connected to an HRC Fused and Isolated supply rated at 10A for 230v or 16A
for

120v.

This equipment is fitted with RFI suppression circuitry. Any check of the electrical insulation by means of high
voltage dielectric testing (for example as in BS EN 61010-1) must be carried out using only a DC voltage.

This unit contains semiconductor components which may be damaged by electric field effects.

16

Safety Warning – Disconnection from Supply

Always ensure that the furnace is disconnected from the supply before repair work is carried out.

Safety Warning - Refractory Fibrous Insulation

This unit contains refractory fibers in its thermal insulation. These materials may be in the form of fibre
blanket or felt, vacuum formed board or shapes, mineral wool slab or loose fill fibre.

Normal use of the furnace does not result in any significant level of airborne dust from these materials, but
much higher levels may be encountered during maintenance or repair.

Whilst there is no evidence of any long term health hazards, we strongly recommend that safety
precautions are taken whenever the materials are handled.

Exposure to dust from fiber which has been used at high temperatures may cause respiratory

disease. When handling fiber always use an approved mask, eye protection, gloves and long sleeved

clothing.

Avoid breaking up waste material. Dispose of waste fiber in sealed containers. After handling

rinse exposed skin with water before washing gently with soap (not detergent). Wash work

clothing separately.

Before commencing any major repairs we recommend reference to the European Ceramic Fibre Industry

Association Bulletin No. 11 and the UK Health and Safety Executive Guidance Note EH46. We can

provide further information on request.
