Supply power vVBATT
– JD
Operation From 7 to 32Vdc with continuous operation.
Protection against polarity reversal with built-in self-
resetting fuse.
The operation is guaranteed during the engine start up to
Vbatt=5VDC for an undefined time.
The device identifies the plant operation at 12 or 24V to
manage its alarms when powered up and whenever
OFF/RESET mode is selected.
Power consumption in stand-by: For HS315 without options:
330mA @ Vbatt =13.5VDC with LCD backlight lamp
310mA @ Vbatt =13.5VDC without LCD backlight lamp
195mA @ Vbatt =27 VDC with LCD backlight lamp
185mA @ Vbatt =27 VDC without LCD backlight lamp
Maximum power consumption during operation
(relays, horn, LCD backlight lamp, digital inputs
activated; static outputs not activated) For HS315 without options:
Max 970mA @ 7 VDC
420mA @ 27 VDC
540mA @ 13.5 VDC
