Recording operating hours
The device records the operating hours of the compressors and fans; This data is visible in the Hr folder and is called
CP0n (nth compressor hours), Fn0n (nth fan hours).
For values lower than 9999 the entire value is displayed, for higher values the hours/100 are displayed and the
decimal point is activated. The maximum limit of recorded hours is 65535; once this value has been reached the
device will automatically reset the hour counter. The display is dynamic, e.g. only the hours of actually available
resources will be displayed. It is possible to set a maximum operating hours threshold, which generates an alarm as
soon as it is reached (for example, for compressor or fan maintenance)
The alarm does not cause the exclusion of the regulator resource, and is displayed on-screen with a code depending
on the resource that has exceeded the permitted operating hours. The alarm does not reset the operating hours.
The operating hours can be reset manually from the states menu, Hr folder; When displaying the hours of a
particular resource, press and hold the “set” key to zero the operating hours of the resource (and not those of
other resources).
Real Time Clock (RTC)
The device can be supplied with a clock which makes it possible to store the time at which alarm events occurred.
The parameter CF72 is used to activate/deactivate the clock.
The current time is set using the appropriate menu as shown in the navigation menu diagram; use the Set key to
confirm the value once the time and date have been modified. The value will only be saved on exiting the menu
(timeout or by pressing the Esc key).
Once the time is set, the instrument must be connected for several hours to fully charge the back-up battery.
The switch between legal/solar time is not automatic.
The device does not perform a real time control on the correctness of the date set; this means that it is
possible to set a non-existent date such as 30/02/2007 without the machine noticing.
