Monitoring functions
DanTaet WLP-1 continuously monitors the installation for leakage
according to a number of adjustable parameters. Up to seven
monitoring methods may be active at any instant, five of which
are phased, i.e. each method has two sets of monitoring
parameters for use in low/high consumption phases respectively.
An integral day/week clock with battery backup and a programmable timer,
or an external signal governs phase changes, permitting continuous monitoring
also in installations exhibiting large day/night consumption varations.
Override function:
Monitoring functions a-f may be overridden by a timer and/or an external signal,
or from the front panel for a predetermined time, or until manually reactivated.
Override is indicated in the display.
Calendar function:
Using calendar function, monitoring phase may be forced by up to 30 user events,
such as e.g. holiday, party or conference.
Each event can request monitoring in low phase, high phase,
double or triple high phase condition.

Alarm functions
Cut-off:
Cutoff valve is closed on alarm, unless it is forced open by a higher priority signal,
such as e.g. Fire Alarm. In particular the system's cut-off valve may be supplied with
an SRNO actuator to force the valve open on power failure.
Alarm is indicated on the front panel and audibly, and a detailed
error description is offered in the display.
Alarm Outputs:
WLP-1 is equipped with four uncommitted switching alarm relay outputs,
all of which may be configured to activate on any error type in any channel as desired.
Remote Signalling:
WLP-1 may be delivered with a GSM/GPRS
modem, whereby on alarm a callout can me made to modems or other technical equipment,
or a text message can be sent to a mobile phone.
Warning function:
Monitoring functions a, b, d, e, f and g may provide early warning via an
alarm relay output at a limiting value adjustable 0-100% of the alarm level.
