When Alarm 1 or Alarm 2 is ON, the PV color turns from
green to red.
When Alarm 1 or Alarm 2 is ON:
Orange Red
When alarm OFF: Orange
When Alarm 1 or Alarm 2 is ON, the PV color turns from
orange to red.
PV color changes continuously
(Orange Green Red)
PV color changes depending on the color range setting.
• PV is lower than [SV-PV color range]: Orange
• PV is within [SV PV color range]: Green
• PV is higher than [SV+PV color range]: Red
(Fig.
6.3-4)

PV color changes continuously
(Orange Green Red),
and at the same time Alarm 1 or
Alarm 2 is ON (Red).
PV color changes depending on the color range setting.
When Alarm 1 or Alarm 2 is ON, PV display turns red.

Hys: Set point of PV color range
A1: Alarm 1 value (High limit alarm)
A2: Alarm 2 value (Low limit alarm)
[OUT1 rate-of-change]
For Heating control, if PV is lower than SV, output is generally turned from OFF to ON as shown in (Fig.6.3-6).
If OUT1 rate-of-change is set, the output can be changed by the rate-of-change (Fig.6.3-7).
This control is suitable for high temperature heaters (which are made from molybdenum, tungsten or platinum,
etc., and used at approx. 1500 to 1800 ) which are easily burnt out from turning on electricity rapidly.
