Units
In the "Units of measurement" menu
item, the display units can be selected
for pressure, length, volume and
dilution.
Sensors
In the menu item "Sensors" the three
additional temperature sensors can be
activated.
In addition, the OS1 and OS 2 current
sensors can be activated.
In the standard version, the sensor
inputs OS1 and OS2 can be provided
with an "additional pressure
monitoring" or with an "additional
purging" function
Application as “additional pressure monitoring“
The APEX Ex p control unit with additional pressure monitoring is based on the
standard version. Purging and the operating phase takes place in the same way.
The difference to the standard version is seen during the operating phase; the
control unit uses two optionally connected pressure sensors to additionally
monitor the equipment in terms of minimum pressure during the operating
phase.
Procedure:
Connect the computer to the Ex p control unit
Activate the programming switch
Log into the WEB interface at the user level
Select the “Extended / sensors” menu
In the table shown you can activate the “Pressure sensor” function
under Current sensor 1 or Current sensor 2. The minimum and
maximum measurement range of the sensor must also be entered.
Confirm the pop-up window with changed value(s)
