The words that appear on three digit display assume the following meaning:
ICF: PT100 probe failure due to interruption or absence of probe.
SCF: PT100 probe failure due to electrical short circuit.
rES: memory resetting of the failure probe effected.
FAn: cooling system status referring to a specific channel.
CH(n): State of a specific channel n (1-8).
PrE: pre alarm relay.
ALL: alarm relay.
AIr: fan cooling system relay.
FLt: FAULT relay.
PROGRAMMING
Push and hold together the buttons UP and DOWN for programming menu.
The functions of the buttons in this phase are indicated as follow: button UP increases
the proposed value, button DOWN decreases the proposed value, button
ENTER/TEST confirms and switches to the next step.
The programming procedure begins with the choice of F parameter.
F=0: group of eight active channels, only one level for alarm and pre alarm valid for all
channels, fan cooling system function deactivated. With F=0 is possible to set only P
and A parameters.
F=1: group of eight active channels, only one level for alarm and pre alarm valid for all
channels, active fan cooling system with only one level valid for lighting H and swithing
off L.
With F=1 is possible to set only four parameters: P, A, L, H.
F=2: group of eight active channels, only one level for alarm and pre alarm valid for all
channels, active fan cooling system with only one level valid for lighting H and
switching off L, control of fan cooling system also with time parameter t.
With F=2, in addition to the parameters set with F=1, is possible to set a parameter t in
minutes, t is the minimum time that must elapse before the device turn off the fan
cooling system. This guarantees a minimum time of activation for fan cooling system
independently from the value of L.
F=3: Independent programming for each channel of all levels P, A, L, H; in this mode it
is also possible to accede to RS485 section. With F=3 the device asks in sequence the
following parameters: Time t in minute, t is the minimum time that must elaps before
