LU-VE Emeritus LU1W Manual De Usuario página 171

In these units, a high-pressure pump is commanded to supply the spray system, which is activated after a PR10 second
time from the control of the first spray valve (to consider the possible stroke time of the motorized valve, if present).
The system can acquire any alarm contact in the pump or in the dedicated control panel; when the pump alarm
occurs, the spray resource is blocked until the problem is resolved and the manual reset of the alarm (see chapter 13
ALARM). You can enable or disable the pump alarm acquisition via parameter PA02; parameter PH44 defines the
polarity of the alarm contact (N.C. set logic → contact open = alarm, closed contact = pump ok).
