If HOLD has been canceled,ON delay is activated as soon as the measured value goes into the alarm band.Cautions on alarmsNo.CautionsItems/Classification1 Note that the ON delay function is effective for alarm in error status. Alarm in errorstatus2 Even during "Err" display, alarms in error status work.Alarm at error3 Even when “LLLL” or “UUUU” is displayed, an alarm function works normally. indication4 Alarm action type codes in No.12 to 15 are also included in No.24 to 27.It is, therefore, recommended to use No.24 to 27. In addition, please notewhen selecting No.12 to 15, setting in ALM2, dLY2, and A2hy are effective.Alarm action typecode5 With the HB alarm, ON delay function, de-energizing function and latchfunction cannot be used.HB alarm6 The minimum alarm set value is –199.9. Alarm set value7 As the alarm action type changed, the alarm set value may also bechanged accordingly.8 Note that all of alarm outputs are not provided at the standby condition. Alarm at standby910Error status alarm is not provided at the standby mode.The HOLD function is effective even if the PV value is in the hysteresis areawhen the power is turned ON.mode.– 22 –
6-5 Ramp/soak function [option]1. FunctionChanges the set value (SV) as the time elapses according to a predetermined program pattern, as shownbelow.Either 4 ramp/soak x 2 patterns or 8 ramp/soak x 1 pattern can be programmed. The first ramp starts fromthe process value (PV) just before the programming is executed.SV-8SV-7SV-3SV-4SV-2SV-5SV-1SV-6PVTM1rTM1s TM4rTM4s TM5r TM5s TM8r TM8sTime1st 4 ramp/soakand/or2nd 4 ramp/soak8 steps2.
