General

The SPS5.7 is a program controller designed for pottery, ceramics & glass firing. Its large illuminated 32 character display makes it easy to set up & use. Setting up is performed using an on-screen menu system and during firing full status information is displayed.

Programs

10 programs are provided. The programs are fully adjustable and each can contain from 1 to 9 ramp/dwell (soak) segments. Controlled heating & cooling ramps are possible. Program linking is provided where up to 9 programs can be linked (in any order) for long complex firings such as are used in glass making.

For convenience the controller is provided with pre-loaded programs. These programs cover the majority of common firing requirements and have been choosen to give safe repeatable results over a wide range of sizes, sections & material types. These programs can be altered or deleted as required.

Options

Internal Trip

This is an adjustable safety device which cuts off heating power in the event of over-firing. A normally hidden FAULT legend illuminates. See trip data for more details.

Auxiliry Relay

This can be user configured as either a damper control, set point alarm or event relay.

Cable & Connector

This is a 2m or 3m cable fitted with a standard Harting HAN 7D style connector.

Mating pre-wired kiln connectors can also be supplied.

Segment Details

A program segment is a ramp followed by a dwell (soak). Both controlled heating & controlled cooling ramps are possible. The ramp rate can be set in the range 1 to 998°C/hour. Setting a ramp rate of 999°C/hour causes full power heating or zero power cooling as required. The target temperature can be set in the range 0 to 1310°C. The dwell time spent at this temperature can be set in the range 00:00 to 99:59 hours:mins. A program comprises 1 to 9 such segments.

Typical Program

Program Segments

A firing program comprises 1 to 9 segments. Entering 0°C for a segment temperature terminates the program & natural cooling follows. In the above example segments 1 to 4 are used & the temperature for segment 5 has been set to 0°C.

To skip a dwell (as in segment 1 above) a dwell time of 00:00 is entered.

To specify a cooling ramp (as in segment 3 above) the segment temperature entered is less than the previous segment's temperature.

Start Delay

The start of a firing can be delayed in the range 00:00 to 99:59 hours:mins.

Program Linking

Up to 9 programs can be linked (in any order) to form a continuous firing sequence. The maximum firing complexity is thus 81 ramp/dwell segments. Typical linking display
