temperature gets lower than all L values
H: High level for cooling system switch on, the AIr relay switch on when the
temperature gets higher than any H value
t: min. time that must elapse before the device turn off the fan cooling system (see
programming details for more information)
S: RS485 speed (see details to chapter PROGRAMMING)
d: answer delay on RS485 serial communication interface in hundredths second
(see details to chapter PROGRAMMING)
U: Address of device on RS485 network
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.
Push and hold together the buttons UP/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
