Operation of the auxiliary relays
Depending on the controller model, it may have 1 or 2 auxiliary relays. The function of these relays is configurable
through the parameters menu.
AUX 1 relay
Ÿ
Deactivated
(
o00
=0): It does not carry out any function.
Ÿ
Compressors / crankcase resistor
(
o00
=1): Controls compressor operation. When the compressor is not
in operation, it powers the crankcase resistor. This function can only be selected via the initial wizard (
In{
).
Ÿ
Light
(
o00
=2): This regulates the operation of cold room light (see p. 27).
Ÿ
Virtual control
(
o00
=3): The relay can be remotely activated and deactivated by means of AKONet software.
AUX 2 relay
Ÿ
Deactivated
(
o10
=0): It does not carry out any function.
Ÿ
Alarm
(
o10
=1): This activates the relay every time that an alarm occurs (see p. 26).
Ÿ
Light
(
o10
=2): This regulates the operation of cold room light (see p. 27).
Ÿ
Virtual control
(
o10
=3): The relay can be remotely activated and deactivated by means of AKONet software.
Ÿ
Door frame resistor
(
o10
=4): This controls the operation of the cold room’s door frame resistor (see p.18).
Ÿ
Defrost 2º evaporator
(
o10
=5): This controls the defrost resistors of a second evaporator (see p. 23).
Ÿ
Same as solenoid status
(
o10
=6): Imitates solenoid status: active if the solenoid is in ON mode, inactive if
the solenoid is in OFF mode.
Ÿ
Same as unit status
(
o10
=7): Indicates the unit’s status: active if the unit is in ON mode, inactive if the unit
is in Stand-by mode.
Ÿ
Drainage resistor
(
o10
=8): Controls the activation/deactivation of the evaporator drainage resistor (see
page 22).
