When not firing there are no indicators lit on
the mimic panel, the run indicator is off and
the display shows the current kiln
temperature.

Altering a program

The controller settings can be reviewed by pressing the

► key.

The first push of the

► key flashes the

program number display. The required firing
program can now be selected with the

▲ & ▼

keys.

Note: holding down the ▲ or ▼ keys causes rapid change of the displayed value.

The next push of the

► key displays the ramp

rate in the range End, 1-999°/HR or FULL.
This can be altered with the

▲ & ▼ keys.

The heating ramp or the cooling ramp indica-
tor on the mimic panel will flash. End marks

the end of the program. FULL heats or cools as fast as possible.

The next push of the

► key displays the soak

temperature. This can be altered with the

▲

▼ keys. The soak temperature indicator on

the mimic panel will flash.

The next push of the

► key displays the soak

period in hours:minutes. This can be altered
in the range 00:00 to 99:59 with the

▲ & ▼

keys. The soak period indicator on the mimic
panel will flash.

The next push of the

► key increments the segment number digit and

firing data for the next segment can be entered.

Program data entry is terminated if End is
selected for a ramp rate with the

▼ key. Pro-

gram data entry is also automatically terminat-
ed if the maximum number of segments have
been entered.

Note 2: to exit programming without cycling through all of the above steps wait 20 seconds without pressing any

keys - the ST215 will revert to the idle display. Alternatively press the

►

key to exit programming and to begin

firing immediately.

Note 3: the ◄ key can be used to reverse through the programming steps to correct errors or to exit programming

mode.

Note 1: available ramp rate displays are: End, 1 … 999 & FULL. If End is shown but another segment is required

then push the ▲ key to obtain the required ramp rate (in the range 1°/hr to 999°/hr). If full power is required then push

the ▲ key until FULL is displayed. To mark the end of the program push the▼ key until End is displayed
