the other LEDs will indicate the reason of failure. In this case the device will not be
operable and should be returned to SPECS for service.
If no LED flashes at all, the presence of the 24 Volt power supply should be checked.
Contact SPECS for furter advice.
1.6.3 Power Requirements
The EC10 needs a 24 Volt supply voltage. Usually this voltage is provided by the HSA

socket labelled “24V” at the front side of the housing as well. The typical current
drain of the device is 48 mA.
