Hood Heaters

By default 0, no hood heaters are used. The hood heater option is factory
installed and may be used or disabled in the CONF session. All the
PWD22/52 heaters are switched ON below 2 °C and off at 5 °C. When
using hood heaters, a separate 24 V heating power must be supplied.
Hood heating power is 30 W for each hood.

BAUD

The baud rate and communication type can be changed by the following
operator command:
BAUD value communication_type
Baud rates 300, 1200, 2400, 4800, 9600
Communication types E (7E1) and N (8N1)
The new value is saved in EEPROM and it is used also after reset or
power up. The default baud rate set at the factory is 9600 bps (7E1). The
communication type definition is optional. It does not change if the baud
rate is changed.
The BAUD command displays the current baud rate and communication
type.
BAUD RATE: 9600 E71

The analog output connection is set at the factory as shown in Figure 17
