IC-610 - Intelligent Control
2.3.5 Safety Control Backup.
A safety control backup is strongly recommended to
ensure a safe environment. The use of an alarm,
warning device or other backup device, which can
detect equipment failure, blown fuses and/or tripped
breakers, helps to prevent harm or damage to the
building and its contents. The safety control backup
wiring, illustrated in figures 3 and 4 and the following
guidelines, will help you avoid serious consequences.
a) BACKUP POWER SOURCE. A backup relay (DPDT)
connects to the power source 1 in normal
operation but will switch to the power source 2 if
source 1 is disabled. The backup relay should
be selected to ensure it is able to support the
required power load (see figure 3).
b) BACKUP THERMOSTAT. It is also strongly
recommended to put a thermostat to at least
one fan parallel to the IC-610 module output
(see figure 4). If the Intelligent Control fails, the
backup thermostat will activate the dedicated
fan at full speed as soon as temperature
reaches the set point of the thermostat. The
thermostat should be accessible for adjustment
and should be set at 3 to 5 degrees above the
fan’s relative set point.
2.3.6 Terminal Block Connections.
The IC-610 terminal block comes with 4 connections for
control modules: P1 to P4 (see figure 2). Each module
must be wired to its own terminal. Refer to the
configuration document and wiring diagrams supplied
for your equipment.
