Program Settings
Programs 9 different temperature profiles can be
entered and stored.
Delayed Start of program up to 99 hrs, 59min.
Ramp Rates adjustable: 0.1 to 3200°C/hr, or FAST
for maximum ramp rate or End to skip remaining
stages.
Hold Temperatures adjustable: -50°C to 3200°C
for thermocouple inputs or –50.0°C to 320.0°C for
RTD input, or PASS to bypass the stage.
Hold Times adjustable: 0:00 to 54:00 hrs:min, or to
Hold indefinitely.
Vent The close and open vent temperature adjust-
able over the Hold Temperature range.
Controller Settings
Inputs
Thermocouple Five user selectable types. Factory
set to Type R. All thermocouple ranges are ambient
temperature compensated. Accuracy ±0.2% of full-
scale ±1°C.
Resistance Thermometer Pt 100 to DIN 43760, 2
or 3 wire connection. Accuracy ±0.2% of full-scale
±0.1°C.
Input Sensor Range
Sensor Type Range
Type J Iron-Constantan –50ºC to 1000ºC
Type K Chromal-Alumel –50ºC to 1250ºC
Type N Nicrosil-Nisil –50ºC to 1300ºC
Type R Platinum, 13% Rhodium-
Platinum
–50ºC to 1750ºC
Type T Copper-Constantan –50ºC to 400ºC
PT100 Resistance Thermometer -100.0°C to320.0°C
Other Settings
Auto Continue After Power Failure When set ON,
program will resume automatically after a power
failure.
Hold Temperature Min/Max Setting Range Ad-
justable from -500°C to 3200°C for thermocouple
inputs, or -50.0°C to 320.0°C for RTD input. Factory
set 0°C to 1300°C.
Loss of Control Timeout If kiln temperature has
not reached Control Temperature within the timeout
setting, the rate of temperature change is checked
against the Ramp Rate Threshold setting and if out
of control firing is stopped. Timeout adjustable from
0:10 to 12:00 hr:min or to OFF, factory set to 1hr.
Auto Simmerstat A time proportioned automatic
simmerstat, (30 second cycle time for relay output
and 2 second cycle time for logic output), reduces
power below the full power limit, factory set to
200ºC. When heat is called for simmerstat gives
10% power at 20ºC, 50% at 100ºC, and 100%
power above 200ºC. Adjustable: 30ºC to 3200ºC
and OFF.
Demo Mode Allows features of the controller to be
demonstrated without heating the kiln.
Outputs
Relay outputs have isolated clean contacts for gen-
eral use rated at 250Vac 2A.
Heat Relay for ON/OFF control. Output is turned off
when kiln temperature is equal to or greater than the
profile temperature and is turned on when kiln tem-
perature falls 2ºC less than profile temperature.
Run Relay option OP-1 Contacts close during firing
and open when completed.
Vent Relay option OP-1 Contacts close when kiln
temperature exceeds the close temperature setting
and open when firing is completed and temperature
has dropped below the open temperature setting.
Alarm Relay option OP-1 When firing fault de-
tected contacts close until alarm is acknowledged.
Logic Heat output logic signal of 5V 20mA maxi-
mum, suitable drive for solid-state relays.
General
Stages 6 stages, each stage comprises Ramp
Rate, Hold Temperature and Hold Time.
Display 4 digit, 14mm high red LED main display
plus 2 digit, 7mm high status display.
Housing Panel mounted according to DIN 43700.
IP65 Facia with polyester membrane covering.
Connections via rear plug-in terminals. Shipping
weight <0.5kg, volume 1.5 litres.
Environment Ambient temperature range 0 to
45°C. Humidity <90% (non-condensing).
Power Supply Standard is 240Vac +10% -15%, 5VA
maximum. Refer to Ordering for other options.
