PH-
Turning on the lamp ( LON+ , LON- )
Supply a voltage of between 5V and 15V. Internally there is an optocoupler diode with a resistance of 1KOhm.
Lamp turned on ( LOK+ , LOK- )
When the lamp is turned on a transistor closes down. Internally there is an optocoupler transistor which can drive a maximum current of up to 2mA.
Lamp not turned on correctly ( LFAIL+ , LFAIL- )
A transistor closes down when the lamp is unable to turn itself on. Internally there is an optocoupler transistor which can drive a maximum current of 2mA.
Lamp current set up ( DAC , 0 )
Supply a voltage of between 1 to 5V in order to have a current of 5 to 25 A. Voltages outside the range of 1 to 5V will be ignored.
Current reading ( ILAMP , 0 )
The current which circulates in the lamp is indicated by a voltage with a conversion of 5 A/V.
Voltage reading ( VLAMP , 0 )
A voltage with a ratio of 1:30 shows the voltage at the edges of the lamp.
Overheating ( TEMP+ , TEMP- )
A transistor closes when the lamp is being protected from overheating. Internally there is an optocoupler transistor which can close off a current of up to 2mA.
Absence of mains ( PH+ , PH- )
A transistor closes when one or more phases in the mains line are missing. Internally an optocoupler transistor is present which can close off a current of up to 2mA.
Service voltage ( +5V , 0 )
This voltage can be used for external circuits with a load of maximum 50mA. Internally there is a 78L05 regulator.
