6.2.5 Expansion Box PN224920 – Single Analogue Input
The single 4-20 mA input expansion box is treated slightly differently to the other expansion boxes as it
needs configuration that is similar to a sensor.
Therefore to add this box to the 7300w² Monitor go to the Sensor Config menu and select 'Add
Sensor'.
The monitor will scan the Modbus addresses and will find PN224920 at Modbus address 39. If multiple
boxes of the same type are to be added then please change the Modbus address to a free number as
explained in other parts of this manual.
As part of the sensor addition a default measurement will be added, this can be configured as follows:
•
Title – select from the list, or create a 'User Defined' title
•
Units – select from the list, or create a 'User Defined' title
•
Set 4mA/20 mA – this allows you to create an offset at 4mA or 20 mA to cater for inaccuracies in the
sensor being attached to our monitor
•
Average – see section 6.3 below
•
Display Position – see section 6.3 below
•
Remove – see section 6.3 below
