It is necessary to inspect the device at the time it is delivered to ensure that the relays have not been damaged during transport. If any defect is found, the transport company and FANOX should be informed immediately. If the relays are not for immediate use, they should be returned to their original packaging.
Fanox Electronic, S.L. adheres itself to the 1st additional disposal of the Spanish 11/97 Standard in which it is said that the final user of the containers should give them, properly segregated by materials, to an authorized recovery, recycler or valuer company.

If no breaker contacts are used, the monitoring of the circuit breaker is made through the current measurement. This is, if less than 0.8% of rated current is detected it is considered the breaker is open and if more than 0.8% of rated current is available, it is considered the breaker is closed. www.fanox.com Rev.04 36/112...
Page 37
If only the circuit breaker 52a contact is available, it should be wired to the corresponding physical input. This physical input is then assigned to the "52a Input” logical input. The 52b logical input is calculated internally as the negative of 52a. The circuit breaker performance is shown in the following finite state machine: www.fanox.com Rev.04 37/112...

52a contact to the "52a Input" logical input, and the circuit breaker 52b contact to the "52b Input" logical input.

The circuit breaker performance is shown in the following finite state machine: www.fanox.com Rev.04 38/112...
It works like a time accumulator, to be active it needs to detect openings within the range defined by these two settings. When this number is exceeded, the ‘Openings/Time Alarm’ status is activated, and its corresponding event is generated. This alarm resets itself, when the corresponding time is exceeded with less trips than those indicated. www.fanox.com Rev.04 39/112...
It must be possible to block the recloser, specially is maintenance tasks are carried out on the substation. To achieve this, there is two logical signals 79Block Command and 79Unblock Command where up to 4 logical inputs can assigned to each one. By default, they are configured as follows: www.fanox.com Rev.04 40/112...
Page 41
Also, this logic signal can be configured to change the Settings Groups through PGC. This can be useful to achieve a fast tripping of protection functions in Hot Line Tag Mode. The auto-recloser´s start up is shown in the following figure: www.fanox.com Rev.04 41/112...

When blocked, the recloser has are two possible paths, depending on if the locked mode is the result ✓ Circuit breaker closing (from manual or remote control): it switches to Standby ✓ Unexpected condition from a reclose cycle: it switches to Safe time. www.fanox.com Rev.04 42/112...

Once the circuit breaker is closed, CLP function picks-up and ‘Cold load time’ starts to count. During this time the relay will work with the new setting group regardless of the circuit breaker situation, this is, without taking into account whether the circuit breaker is maintained closed or is open. www.fanox.com Rev.04 45/112...
Switchgears have a limited opening current, so the fuses are responsible for cutting out the circuit for high current short circuits, as the switchgear would be destroyed if opened in this situation. In order to deal with these situations, tripping is blocked when the phase current exceeds a pre-set value. www.fanox.com Rev.04 46/112...
