the relay operating mode has been configured using the installer
parameter ' Relay latch '.
If the human intervention is required to reset to normal operation
mode the entire system, after resolving the cause that triggered the
alarm and/or fault state, it is necessary that the user intentionally
pushes for 3 seconds the '
reset
' button. By resetting the alarms,
all the events stored in the unit will be erased.
On the contrary, if the human intervention is NOT required to reset
the normal operation of the entire system, after resolving the cause
that triggered the alarm and/or fault condition, the unit goes back to
its normal operation mode.
WARNING
- The events detected by the control unit can be reset even if
they have not been visualized by briefly pressing the “enter”
button: so, it is advised to scroll among all the stored events
before pushing the “reset” button.
Relay automatic reset
Pre-alarm relays action could be 'auto-resetting' in case the
latching parameter (in
Relay latch - Latch pral
) has been set to
'
N
'. Please refer to proper section for further details.
The action of the auxiliary relays can be 'self-resetting' when the
'latch' parameter (in
Relay latch - Latch aux1 / Latch aux2
) has
been set on '
N
'. Please refer to proper section for further details.
Alarm relays action could be 'auto-resetting' in case the latching
parameter (in
Relay latch - Latch alr1 / Latch alr2
) has been set
on '
N
'. Please refer to proper section for further details.

[c] MESSAGES DISPLAYED ON THE CONTROL UNIT
─────────────────────────────────────────────────
Below are the messages highlighted on the control panel display in
different conditions. It is assumed that Zone 1 is set for Methane
and that the concentration is variable.
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║S1 CH4 none ║
Explanation:
'Disabled area'
The relevant zone has not been activated. Remember that once a
transmitter has been wired to an input the relevant zone must also
be activated in configuration.
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║S1 CH4 0.0LEL M║
Explanation:
'Normal operation'
This is what display shows during normal operation.
Concentration detected in this example is 0% L.E.L.
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║Zone 1 : loop ║
The yellow led is lit in correspondence with the symbol '
' and the
buzzer sends a continuous tone.
Explanation:
'Fault in the current loop line'
Cable connecting the transmitter to the control unit present either a
short or an open circuit failure between any of the sensor wires.
Check and repair the current loop line regarding the faulty zone.
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║S1 CH4 ---- F║
The yellow led is lit in correspondence with the symbol '
' and the
buzzer sends a continuous tone.
Explanation:
' Fault on the gas sensor '.
The gas sensor is faulty, and so it is imposing 2mA on the current
loop. Check the faulty transmitter and, if the case, change it with a
new one.
─────────────────────────────────────────────────
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║S1 CH4 15.2LEL P║
The red led flashes in correspondence with the symbol '
' and the
buzzer sends an intermittent tone.
Explanation:
'Pre-alarm state'.
The prealarm concentration threshold in the zone under monitoring
has been exceeded. In this example a prealarm threshold of 10%
L.E.L. has been assumed (default factory value).
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║S1 CH4 25.2LEL A║
The red led lights up in correspondence with the symbol '
' and
the buzzer emits a continuous tone.
Explanation:
'Alarm 1'.
The detected concentration exceeded the alarm threshold 1 in the
controlled area. In this example, a threshold value of 20% L.E.L.
(Factory value). The alarm relay, red led and buzzer are kept active
until the reset key is pressed.
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║S1 CH4 30.5LEL H║
.
The red led lights up in correspondence with the symbol '
' and
the buzzer emits a continuous tone.
Explanation:
'Alarm 2'.
The detected concentration exceeded the alarm threshold 1 in the
controlled area. In this example, a threshold value of 30% L.E.L.
(Factory value). The alarm relay, red led and buzzer are kept active
until the reset key is pressed.
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║S1 CH4 OVR ║
The red led lights in correspondence with the symbol '
' and the
buzzer emits a continuous tone.
Explanation:
'Over Range state'
The upper limit of the measuring range has been exceeded.
Alarm relay, red led and buzzer and indication 'OVR' are latched as
active until the reset button is pressed.
─────────────────────────────────────────────────
Message displayed:
╔════════════════╗
║MEMORY FAULT: 01║
║CONTACT SERVICE║
╚
════════════════
╝
Explanation:
'Memory fault'.
An error in one of the internal memories has been detected. The
operation is not reliable anymore.
Contact service for device replacement. The codes are reported on
the table “Unit fault condition”.
─────────────────────────────────────────────────
[d] ANOMALOUS EVENTS PRIORITY
─────────────────────────────────────────────────
The different conditions, previously descripted, linked to the
different events will have the following priority order (1 max. - 8
min.):
CONDITION
PRIORITY (1=MAX)
Unit Fault
1
Open Loop
2
Transmitter Fault
3
Sensor end life
4
