Measuring Inputs

Thermocouples
Burnout: open input circuit detection (wires or sensor) via overrange or underrange indication.
Cold junction: automatic compensation from 0 and 50°C ambient.
Cold junction compensation error: 0.1°C/°C.

RTD
Type: PT100 3 wire connection.
Measuring current: 135 µA.
Line resistance: automatic compensation up to 20 W/wire with an error <±0.1% of the input span for the range -19.9 to 99.9°C. (No measurable error for other ranges.)
Engineering units: programmable °C or °F.
EBurnout: detection of the sensor and of one or more wires open circuit. Shows short circuit when sensor resistance is lower than 15 W.

Logic Input
Type: Dry contact (no voltage)
Functions:	- Setpoint select (SP1/SP2)
	- Timer mode 1 - reset - Timer mode 2 - start - Timer mode 3 - start - Timer mode 4 - start

Control Action

Algorithm: PID + SMART Tune.

Derivative time: from 0 to 10 minutes.

Integral preload: - for one control output, from 0 to 100% of the output range
-for two control outputs, from -100% to 100% of the output range.

Heating cycle: from 1 to 200 seconds.

Cooling cycle: from 1 to 200 seconds.

Relative cooling gain: from 0.20 to 1.00.
