104 Connecting to power supplyVEGAPULS 61 • HART and accumulator pack47099-EN-1602154 Connecting to power supply4.1 Connection of the battery chargerWe recommended charging the integrated accumulator completelybefore setting up the instrument. You can find the charging time inchapter "Technical data".The battery charger is plugged into a socket in the supply room, seechapter "Wiring plan".The LEDs in the supply room show the charging process and condi-tion of the accumulator, see chapter "Wiring plan".4.2 Wiring plan24350516273849modes4 ON/OFF3 ON/OFF 1h1,2 OFFCharge Accu5..9 auto cycle1 2+( ) (-)1Fig. 6: Supply room1 Internal connection of the socket for the battery charger2 Mode switch3 LED green, charging process4 LED yellow, charging status5 Socket for the battery chargerThe mode switch enables the selection of the following modes:• 0 = sensor off, LEDs show the accumulator status• 1, 2 = sensor off, LEDs off• 3 = sensor on for 1 hour after pressing a key (delivery status)• 4 = sensor permanently on, switching on/off via button• 5 = sensor is switched on every 30 min. for 3 min.• 6 = sensor is switched on every hour for 3 min.• 7 = sensor is switched on every 6 hours for 3 min.• 8 = sensor is switched on every 12 hours for 3 min.• 9 = sensor is switched on every 24 hours for 3 min.The green LED characterizes the charging process:• LED flashes = Accumulator is charging• LED lights = accumulator is full, battery charger should beunplugged (accumulator life time)After pressing the key or changing the mode the yellow LED showsthe accumulator status for approximately 10 s as follows:• LED lights = accumulator is full• LED flashes = accumulator should be chargedSupply room
