It is possible to access the setup menu by pressing both T1 and T2 buttons for 3 seconds. The available options are: language, date, on/off buzzer, alarm history, timers (P1 and P2 working hours and HOT ALERT counter), password, number or pumps (1 or 2), pumps off delay (0 to 60 sec), emptying delay (0 to 60 sec), alarm delay (0 to 255 sec).

Technical maintenance must be performed only by Quality Invents authorized personnel.

The carbon filter on the snorkel of the WRE system must be replaced every 6 months. Authorized technicians must replace it and fill in the label on the filter with the replacement date.
The Quality Invents code for the filter replacement is Q-1320-03.

In the first 2 seconds of boot, the display shows the software version. Then, if there are no alarms, TANK 1 and TANK 2 status are shown.
Any active alarm is cyclically shown.

In order to shutdown the acoustic alarm, press T2 button for 3 seconds. If the alarm is still active, the acoustic signal will be restored after 20 minutes.

It is not possible to power off the main optical signal while an alarm is activated.

Tank status:

The arrow on the right of each tank (T1 and T2) indicates which one is ACTIVATED; it blinks when the relative pump is working.
It is possible to change the pumps status by pressing T1 and T2 buttons simultaneously for 3 seconds.

• AT1 (Slow Buzzer) TANK 1 full
• AT2 (Slow Buzzer) TANK 2 full
• AT3 (Slow Buzzer) No service (T1 and T2 disabled = #)
• AM1 (Fast Buzzer) HOT ALERT on tank level (verify pumps)
• AM2 (Fast Buzzer) Main tank LLD problem
• AP1 (Fast Buzzer) Pump 1 problem
• AP2 (Fast Buzzer) Pump 2 problem
• AT4 (Slow Buzzer) TANK 1 must be enabled (T1 change confirmation, T2 ACTIVE)
• AT5 (Slow Buzzer) TANK 2 must be enabled (T2 change confirmation, T1 ACTIVE)

In the first 2 seconds of boot, the display shows the software version. Then, if there are no alarms, TANK 1 and TANK 2 status are shown.
Any active alarm is cyclically shown.

In order to shutdown the acoustic alarm, press T2 button for 3 seconds. If the alarm is still active, the acoustic signal will be restored after 20 minutes.

• AT3 (Fast Buzzer) No service (Receiver tank level too high)[1]
• AM1 (Fast Buzzer) HOT ALERT – internal tank level too high
• AM2 (Fast Buzzer) Main tank LLD problem
• AP1 (Fast Buzzer) Pump 1 problem
• AP2 (Fast Buzzer) Pump 2 problem

[1] WRE Sender system is normally used with a high capacity tank. Quality Invents produces receiving tanks (from 300 to 2000 liters of capacity) with a management electronic board (My Big Tank versions). With a too high level in the receiving tank, the eletronic board stops the pumps. Third part tanks level sensors can also be connected to a free contact provided by the WRE Sender electronic board.

In the first 2 seconds of boot, the display shows the software version. Then, if there are no alarms, TANK 1 and TANK 2 status are shown.
Any active alarm is cyclically shown.

In order to shutdown the acoustic alarm, press T2 button for 3 seconds. If the alarm is still active, the acoustic signal will be restored after 20 minutes.

It is not possible to power off the main optical signal while an alarm is activated.

LEVEL STATUS: 0% (empty tank) 70% – 90% e 100% (full tank)

• AT1 (Slow Buzzer) Tank Level at 70%
• AT3 (Slow Buzzer) Tank Level at 90%
• AT4 (Fast Buzzer) HOT ALERT – Tank Level at 100% [1]
• AM2 (Fast Buzzer) Main tank LLD problem
• AP1 (Fast Buzzer) Pump 1 problem

[1] With the tank level at 100%, a STOP signal is sent to all of the connected WRE Sender stations. The signal is disabled once the level in the tank is lower than 70%.

In the first 2 seconds of boot, the display shows the software version. Then, if there are no alarms, main tank status is shown.
Any active alarm is cyclically shown.

In order to shutdown the acoustic alarm, press T1 button for 3 seconds. If the alarm is still active, the acoustic signal will be restored (different alarms have different restore timings).

It is not possible to power off the main optical signal while an alarm is activated.

• AT1 (Slow Buzzer) TANK 1 full
• AT2 (Slow Buzzer) TANK 2 full
• AT3 (Slow Buzzer) No service (TANK 1 e 2 disabled = #)
• AT4 (Slow Buzzer) TANK1 must be enabled (TANK1 replaced, TANK2 ACTIVE)
• AT4 (Slow Buzzer) TANK2 must be enabled (TANK2 replaced, TANK1 ACTIVE)
