Loop break alarm (LBA)
It checks control loop and outputs alarm by temperature change of the subject. For heating control (cooling control), when
control output MV is 100% (0% for cooling control) and PV is not increased over than LBA detection band [ LBaB ] during
LBA monitoring time [ LBaT ], or when control output MV is 0% (100% for cooling control) and PV is not decreased below
than LBA detection band [ LBaB ] during LBA monitoring time [ LBaT ], alarm output turns ON.

※ When executing auto-tuning, LBA detection band [ LBaB ] and LBA monitoring time are automatically set based on auto
tuning value. When AL1, AL2 alarm operation [ AL-1 , AL-2 ] is set as loop break alarm (LBA) [ LBa ], LBA detection
band [ LBaB ] and LBA monitoring time [ LBaT ] parameter is displayed.
SSR drive output function (SSRP function) [SSrM]
● S SRP function is selectable one of standard ON/OFF control, cycle control, phase control by utilizing standard SSR drive
output.
● Realizing high accuracy and cost effective temperature control as linear output(cycle control and phase control).
● Select one of standard ON/OFF control [STND], cycle control [CYCL] , phase control [PHAS] at [SSrM] parameter of
Parameter group 2. For cycle control, connect zero cross turn-on SSR or random turn-on SSR. For phase control,
connect random turn-on SSR.
Power
100-240VAC
50/60Hz
※ When selecting cycle or phase control mode, the power supply for load and temperature controller must be the same.
※ In case of selecting cycle [ CYCL ] or phase [ PHAS ] control mode for PID control, control cycle [ T ] is not allowed to set.
※ For AC/DC power model (TC4 - 2R), this parameter [ SSrM ] is not displayed and it is available only standard control
by relay or SSR.
