8.5 Output trim
8.6 detector cleaning
CAUTION
For integral type : Ambient temperature may not exceed 55°C !
The equipment can be CIP-cleaned. Steam below 230°C is not a problem. However, you should take care
that the cleaning operation does not last so long that the converter temperature exceed 55°C.
Switch power off during cleaning.
Output trim With this function the 4 mA and the 20 mA can be adjusted if
required
AO 1 trim 4mA / AO 1 trim 20mA The analog output 1 is set to the 4 mA or 20 mA. Connect a load
resistor between 20 and 600 W and measure the output current.
This current value must be entered on request on display.
The deviation to 4 mA is corrected by the converter itself.
AO 2 trim 4mA / AO 2 trim 20mA The analog output 2 is set to the internal 4 mA or 20 mA value.
Connect a load resistor between 20 and 600 W and measure the
output current.
This current value must be entered on request on display.
