light glows, indicating that the system
is on.
3.
When operating manually, the controller has two modes;
soak
or
shut-
off
. To select the
soak
mode, depress the pushbutton switch, leaving it
latched in the “pressed’ position. Push the button a second time to release
the latch, leaving the control in the
shut-off
mode.
4.
To
reset
the controller when latched off in the shut-off mode, depress the
pushbutton, then press it again to release the latch.
5.
Adjust the set point knob to the desired soak or shut-off temperature.
6.
In the soak mode, the controller will maintain the kiln’s temperature at the
level you have set. In the shut-off mode, the controller will permit the
kiln’s temperature to rise to the limit you have set, then shut it off,
allowing it to cool at its own natural rate.

INSTRUCTION SHEET
FireRight LT
Temperature Controller
for Ceramic Kilns
GENERAL INFORMATION
The
FireRight LT
Controller is a simple non-indicating temperature controller specially
designed for use with ceramic kilns. Soak and Shut-Off operation is provided for, over a
temperature range of 0 to 2500°F. The controller is provided on a single panel, suitable
for flush mounting on most kiln switch boxes.
The
FireRight LT
can be used to supply power for small kilns, and to operate high
voltage power switching devices on larger kilns, such as definite purpose contactors and
mercury relays. Standard push-on connectors permit wiring for either 110vac or 220vac,
50/60Hz power. A single-pole electrical contact, capable switching up to 15 amps at
240vac, constitutes the controller’s output. Since all but the smallest kilns draw more
than 15 amps, a power relay or definite purpose contactor is normally also required to
complete the installation.
