Alarms

1. Alarms display and Resetting
A fault on a unit will be shown
through the user interface or
through 2 digital outputs, one for
each refrigerant circuit.
The alarms are divided into 3
categories:
- Warning. Shows that something is
wrong on the unit but unit can be
kept in operation. A message is
displayed on the user interface
screen. These messages are not
recorded in the history list.
- Fault with automatic reset: when
the cause of the fault disappears,
the fault is cancelled and unit
operation will return to normal.
The messages displayed on the
user interface screen disappear
but are recorded in the history list
of faults. The fault is relayed
through the digital output if I/O
parameter is set to show a circuit
fault.
- Fault with manual reset: when the
cause of the fault disappears, a
manual reset is required to restart
the unit. The messages displayed
on the user interface screen
disappear and are recorded in the
history list of faults. The fault is
relayed through the digital output
if I/O parameter is set to show a
circuit fault.
Should an alarm occur,
lit in red.
