Specifications

UTC-2030 specifications:

Alarm output: 1 A max, 240 Vac max., 50/60 Hz, SPDT (form C) relay output configured for "fail-safe" operation.

Approvals: CSA "C" - "US" for ordinary locations.

Enclosure: Nema 4, grey painted steel with ¼ turn latch.

Indicator light: Nema 4 multi-function three color LED.

Input voltage range: 120-240 Vac, 50/60 Hz.

Monitoring and alarming: The electronics monitor low temperature, ground fault current, open / shorted temperature sensor(s) and high cable temperature.

Operating ambient: -40 to +40°C (-40 to +104°F).

Power output: 2-pole relay output rated 30 A - 240 Vac.

Terminal blocks:

Factory programmable:

Note: You can use the default settings of the following features by seleccioneing the appropriate program code as shown in tables 5 and 6 (program codes are listed here).

Auto-cycle: When the temperature controller is energised, and then at 24 hours intervals, the controller performs an auto-cycle test by turning on the load to measure the ground fault leakage current. If the measured ground fault current is above the set level, the ground fault current alarm is activated. Can be disabled at the factory upon special request.

Ground fault detection: Factory adjustable to trip and alarm or alarm only. Setting @ 30 or 100 ma.

Remote override: The user may force the unit on/off via a remote dry contact. Factory adjustable to operate in timed (1-48 hours) or continuous mode.

Temperature control : three 3-wire 100 W @ 0°C Platinum RTD (alpha=0,00385 W/W/°C), lead compensated to 20 W per lead. or three 2-wire 2 252 W @ 25°C NTC Thermistor.

Deadband : 1 to 5°C (1.8 to 9°F)

Control temperature setpoint range : -5 to 75°C (23 to 167°F)

Low temperature alarm : Feature can be enabled to provide low temperature alarm on TS1 and TS2.

Low temperature setpoint range : -10 to 75°C (14 to 167°F)

High cable temperature : The third temperature sensor (referred to as TS3) is used as a high cable temperature limit for plastic piping system protection. When Ts3 is enabled, the high limit feature will override demand for heat and shut off the load when a high cable temperature condition is reached.

High temperature setpoint range : 25 to +100°C (77 to +212°F)

UTC-2230 specifications :

Same as the UTC-2030 except for the following :

Circuit breaker : 2-pole, 30 A, 240 Vac, pre-wired to the temperature control board.

Terminal blocks: Incoming power lugs at the circuit breaker for # 14 to # 4 AWG.

Enclosure: Nema 4, grey painted steel with clips.
