5. 4 Cascading control of other units

The steam production reached can exceed the maximum capacity of the

master unit by connecting one or more slaves

- Master: UEX unit with analogue output to control the other units

- Slave: UEX/UEY unit that operates based on the analogue control signal

received from the master

- each UEX master unit can control up to 30 UEX slave units or 14 UEY slave

units.

Parameter P0 on each single unit (master or slave) only a ects the production

on that unit.

If the master is disabled by remote contact or serial connection, production

will stop on the slaves.

Some alarms also stop the slaves (see the table of alarms)
