General Specifications

Model UT150L Limit Controller

GS 05C01E22-01E

■ General

The UT150L is an FM approved limit controller that can be configured either as a high limit or as a low limit controller by a user.

The UT150L features universal input, two alarm outputs, retransmission output, a timer to count the total time the setpoint is exceeded, and a register to retain the maximum temperature reached.

The RS485 communication interface is available optionally.

■ Limit Control Function

When a measured value (PV) exceeds a setpoint (SP), “EXCEEDED” lamp lights, and “OUT” lamp turns ON (A). The limit output relay is de-energized then. “EXCEEDED” lamp turns off when PV goes into normal condition, while the output (OUT) display lamp stays on as it is (B). The output (OUT) display lamp turns off when a confirming operation is done by an operator (C). The way to confirm is pressing the “ ” key (or by an external contact, according to the setting of setup parameter DIS). The confirming operation is not accepted during PV exceeds SP (D) (during EXCEEDED lamp lights*). State of output relay is deenergized whenever “OUT” lamp is on. * Check the “HYS” value if the EXCEEDED lamp is not turn off when PV is lower than SP.
