Principle of the installation of the ducts
Each fan-motor assembly has its own duct
2 fans can used the same duct
B
Access hatch for maintaining the ventilation components for each duct.
Rules for a correct ductwork
-
each duct must serve a maximum of 2 fans – DO NOT
EXCEED this limit
-
if multiple fans share the same duct, they must belong to the
same refrigerant circuit and the same air-cooled exchanger
system.
IMPORTANT: The duct connections on the units must not
generate any mechanical stress on the fan supporting
structure.
Fan motor electrical protection
In case of a locked rotor or an overload, the motors of each circuit
are electrically protected by the circuit variable speed drive.
Each variable speed drive follows a variable current characteristic,
based on the frequency from 10 to 60 Hz and the number of
controlled fans.
If a fan stops working, the variable speed drive automatically
detects the malfunction.
Refer to the control manual for the list of alarms specific to this
option.
12.2.9 - Pump protection and control options
The pump protection and control options give the customer access to outlets designed for the supply and actuation of pumps
external to the machine.
These outlets provide electrical protection via a thermal-magnetic circuit breaker and a control switch actuated by the machine's
control system.
The protections and controls are sized based on the factory-fitted pumps outlined in the section "Electrical data for the hydraulic
module".
