Temperature Sensor Protections - Vacon NX ACTIVE FRONT END II Applications Manual

Arfiff05 Standard AFE-II

7.7.2 Temperature sensor protections

The temperature protection function is used to measure temperatures and issue warnings and/or
faults when the set limits are exceeded. The AFEII application supports two OPT-BH and OPT-B8
board simultaneously.
P2.7.2.1 Number of used inputs in board 1
Select used temperature sensor combination with this parameter. See also the Vacon I/O
boards manual.
0 = Not used (ID Write, value of maximum temperature can be written from fieldbus)
1 = Sensor 1 in use
2 = Sensor 1 & 2 in use
3 = Sensor 1 & 2 & 3 in use
4 = Sensor 2 & 3 in use
5 = Sensor 3 in use
Note: If the selected value is greater than the actual number of used sensor inputs, the
display will read 200ºC. If the input is short-circuited the displayed value is 30ºC.
P2.7.2.2 Board 1 Temperature responce
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to Stop Function
3 = Fault, stop mode after fault always by coasting
P2.7.2.3 Board 1 warning limit ID741
Set here the limit at which the PT100 warning will be activated.
When individual warning and fault limits are activated this is first board first channel
(1A).
P2.7.2.4 Board 1 fault limit
Set here the limit at which the PT100 fault (F56) will be activated.
When individual warning and fault limits are activated this is first board first channel
(1A).
P2.7.2.5 Number of used inputs in board 2
If you have two temperature sensor boards installed in your frequency converter you can
choose here the combination inputs in use in the second board. See also the Vacon I/O
boards manual.
0 = Not used (ID Write, value of maximum temperature can be written from fieldbus)
1 = Sensor 1 in use
2 = Sensor 1 & 2 in use
3 = Sensor 1 & 2 & 3 in use
4 = Sensor 2 & 3 in use
5 = Sensor 3 in use
