T2S Configuration Parameters
;61; ;ACin Mode (0 : normal, 1 : Safe); ;0; ; ;
¾ Allows to open the ACin inlet relay
¾ 0 normal running in EPC mode
¾ 1 ACin inlet relay is open and so the system is insulated from the Mains
¾ In our circuit, the neutral is common in the whole installation. With this option, ACin line is insulated from its converter.
If DC disappears, the ACin relay switches on and the loads are fed from the ACin source. This transition takes 10 msec
maximum.
;62; ;Walk-in Mode (0 to 60) ; ;0; ; ;
¾ Defines the walking mode configuration. Available from 177 sw version
¾ The Walk-in mode allows the inverter to come back progressively on the AC priority source after an outage. Friendly
use on Genset
¾ 0 no progressive switching
¾ 1 progressive switching at 10% by second for software 177 and 178
¾ Since software version 185.24 it is possible to set the value using formula Delay=A+10*P*(50/f)
• A is the fixed timer for sync average 10sec.
• P (between 1 and 60) to adjust the slope between 0 and 600 seconds
• 1 to 60 (each unity take 10 seconds).
◊ For instance “6” means 60 sec or 1 minute with 6 step of 15%
◊ For instance 10 means 100 sec with 10 steps of 10%
◊ For instance 4 means 40 sec with 4 steps of 25%
;70; ;Number of phases ; ;3; ;;
¾ Sets the number of phases: 1 (Single phase), 2 (2PH), 3 (3PH)
;71; ;Mode ( 0 star ; 1 Delta) ; ;0; ;;
¾ Defines the protection type for working on Delta load.
¾ The ‘Star or Delta’ mode allows to configure the automatic protection when the load is delta connection (engine for
instance). This protects the load when 1 phase is lost. The protection consists of switching off all inverters.
¾ 0 Default setting, and no delta load protection.
¾ 1 Delta load protection available (only use on manufacturer request).
¾ When the load is a mix of Star and Delta it will better to kept the default setting and install a specific protection for
Delta load when 1 phase fails.
