Definition Of The Symbols On The Lc Display - Wilo Stratos Notice De Montage Et De Mise En Service

English
• In the event that one pump experiences a failure/problem, the other will run as
a single pump in standard mode as instructed by the master.
• In the event of a break in communication: The slave pump runs at the last set
value of the master prior to the interruption.
• Pump swap: If only one pump is operational (duty/standby, peak- or low-load
operation), the pumps are swapped after every 24 hrs' of actual operating time.
Both pumps are running at the time of the pump alteration in order to ensure
that operation is not interrupted.
NOTE: Both pumps will always be running if both the manual control mode and
the synchronous mode are active at the same time.
No pump alteration takes place. No pump alteration takes place during the
active night reduction after 24 h of effective running time.
• FC: The collective fault contact (FC) of the master can be connected to a central
control point. In this case, contact is only established with the master. The
reading is valid for both pumps.
As an option, the error message contacts of master and slave can be
programmed as single fault signal with an IR operating and service unit
(accessory). For the single fault signals, contact must be established with each
pump.

NOTE: The legibility of the display is significantly dependent on the observer's
perspective. Wide fluctuations in the ambient temperature accelerate ageing of
the display and can result in restricted legibility of the display.
