If The On-butt is closed before, is cnected to voltage (also when line fault across On-Butt), the output ctacts will not close. A line fault across the On-butt which occurred after activati of the relay, will be detected with the next activati and the output ctacts will not close. If a line fault occurs after the voltage has been cnected to,, the unit will be activated because this line fault is similar to the normal On-functi. The gold plated ctacts of the BG 5925 mean that this module is also suitable for switching small loads of 1 mva - 7 VA, 1 mw - 7 W in the range 0,1-60 V, ma. The ctacts also permit the maximum switching current. However since the gold plating will be burnt off at this current level, the device is no lger suitable for switching small loads after this. The terminal permits the operati of the device in IT-systems with insulati mitoring, serves as a reference point for testing the ctrol voltage and is used to cnect the loop when cross fault mitoring is selected.

To alter the functis automatic start - manual start and with or without cross fault mitoring, the switches S1 and S2 are used. These are located behind the frt cover (see unit programming). The setting with or without cross fault mitoring butts is made with S1. S2 is used to change between automatic an manual restart. On automatic start also the terminals - have to be linked.
