Tuning. Note that the Tuning operation is always performed with
respect to the Control (Main) Setpoint (SP). When, the Auxiliary
Setpoint mode is disabled (by selecting the option to other than
‘Auxiliary Setpoint’) in PAGE-13 parameter list, the controller
treats Control (Main) Setpoint (SP) as an active Setpoint.
ALARM SETPOINT
This parameter is available only if ‘Alarm Type’ is selected to
‘Process High’ or ‘Process Low’. If the alarm type is selected as
‘Process High’, the alarm is activated whenever the measured PV
is at or below the set value. alarm is activated whenever the
measured PV
is at or above the set value. Similarly, if the alarm
type is selected as ‘Process Low’, the alarm is activated whenever
the measured PV
is at or below the set value.
ALARM DEVIATION
This parameter is available only if ‘Alarm Type’ is selected to
‘Deviation Band’ and sets a deviation band above or below the SP
depending upon the Negative (-) or Positive (+) value for this
parameter, respectively. The Alarm is activated if the PV
rises
above (Positive value) or falls below (Negative value) the
deviation band.
ALARM BAND
This parameter is available only if ‘Alarm Type’ is selected to
‘Window Band’ and sets a symmetrical band around the SP. The
alarm is activated if the PV exceeds the band in either direction.
Note:
The Control (Main) Setpoint, Auxiliary Setpoint and Alarm Parameters are
available for adjustment only if their adjustment is enabled under
supervisory level in PAGE-13 parameter list, else available for view only.

PV ERROR INDICATIONS
In case of PV exceeding the Minimum or Maximum Range specified for the selected ‘Input Type’ or in case of input sensor
(Thermocouple / RTD or DC Linear Current/Voltage signal) open / broken; the Upper Readout flashes the Error Messages as
listed in Table 2.2. The Figure 2.2 illustrates an open sensor condition.
