Limits (LOOPM_DT)

  • Hi Hi Lim - This field displays the maximum value of CNTRL1 in engineering units before the high high limit active bit (HI_HI_ACT) is set. Click this field to enter a new limit.

  • Hi Lim - This field displays the maximum value of CNTRL1 in engineering units before the high limit active bit (HI_ACT) is set. Click this field to enter a new limit.

  • Lo Lim - This field displays the minimum value of CNTRL1 in engineering units before the low limit active bit (LO_ACT) is set. Click this field to enter a new limit.

  • Lo Lo Lim - This field displays the minimum value of CNTRL1 in engineering units before the low low limit active bit (LO_LO_ACT) is set. Click this field to enter a new limit.

  • Out Hi Lim - This field displays the maximum value of MNPLT1 in engineering units. Click this field to enter a new limit. The valid input range for this value is -10 to 110 % of the output scale in engineering units.

  • Out Lo Lim - This field displays the minimum value of MNPLT1 in engineering units. Click this field to enter a new limit. The valid input range for this value is -10 to 110 % of the output scale in engineering units.

  • SP Hi Lim - This field displays the maximum value of SP1 in engineering units. Click this field to enter a new limit. The valid input range for this value is -10 to 110 % of the PV Scale in engineering units.

  • SP Lo Lim - This field displays the minimum value of SP1 in engineering units. Click this field to enter a new limit. The valid input range for this value is -10 to 110 % of the PV Scale in engineering units.

  • Alm Hysteresis - This field displays the alarm hysteresis (or deadband) value for the loop alarms in % of CNTRL1 Scale. Click this field to enter a new value. An alarm does not recur until CNTRL1 has backed away from the corresponding limit by at least the % of CNTRL1 Scale specified by this value.
