HB (Heater burnout alarm) setting [ and X.X are indicated in turn.]
• Sets the heater current value for Heater burnout alarm.
Setting the value to 0.0 disables the function.
• Available only when Heater burnout alarm (option) is added
• When OUT1 is OFF, heater current value shows the same value as when OUT1 was on.
• It is recommended to set approx. 80 % of the heater current value (setting value) considering the
voltage fluctuation.
• Self-holding is not available for the alarm output.
• Setting range: Rating 5 A:
0.0 … 5.0 A
Rating 10 A: 0.0 … 10.0 A
Rating 20 A: 0.0 … 20.0 A
Rating 50 A: 0.0 … 50.0 A
• Default: 0.0 A
LA (Loop break alarm) action time setting [
]
• Sets the action time to assess the Loop break alarm.
• Available only when option [2AR] or [2AL] is added
• Setting range: 0 … 200 minutes
• Default: 0 minutes
LA (Loop break alarm) action span setting [
]
• Sets the action span to assess the Loop break alarm.
• Available only when option [2AS] or [2AL] is added
• Setting range: 0 … 150 °C (°F), however, with a decimal point 0.0 … 150.0 °C (°F)
For DC input, 0 … 1500 (The placement of the decimal point follows the selection.)
• Default: 0 °C
[A1, A2 setting range]
(Table 5.3-1)
Alarm action Setting range
High limit alarm –Input span to Input span °C (°F) *1
Low limit alarm –Input span to Input span °C (°F) *1
High/Low limits alarm 0 to Input span °C (°F) *1
High/Low limit range alarm 0 to Input span °C (°F) *1
Process high alarm Input range low limit to Input range high limit*2
Process low alarm Input range low limit to Input range high limit*2
High limit alarm with standby –Input span to Input span °C (°F) *1
Low limit alarm with standby –Input span to Input span °C (°F) *1
High/Low limits alarm with standby 0 to Input span °C (°F) *1
• When the input has a decimal point, the negative low limit value is –199.9, and the positive high limit
value is 999.9.
*1: For DC input, the Input span is the same as the Input range scaling span.
*2: For DC input, Input range low (high) limit value is the same as the Input range scaling low (high)
limit value.
