Electrical connections and parameter configuration

There are 2 relays on the INVERTER. Connecting terminals X7-1-2-3 and X6-1-2-3 are used for:
LMV2/3x: Relay 1 is used as a safety contact on the safety loop series of the equipment. Relay 2 is used as a fault indicator on the
burner panel front.
LMV5x / ETAMATIC: Relay 1 is used as a contact for control of fan motor start. Relay 2 is used as a fault indicator of the INVERTER to
the LMV5x / ETAMATIC equipment.

Relay 2 functions
4.210 V O operation
Automatic reset of faults.
The INVERTER resets the fault after the set time.
Set value = 30 seconds
With the reset function the maximum number of automatic resets can be limited.
Set value = 0 (maximum number of automatic resets)
Select the operating mode of relay 1.
Set value = LMV2x/3x..= 11 (NC inverted error)
Set value = LMV5x / ETAMATIC = 19 (motor is in NO function)
Select the operating mode of relay 2.
Set value = LMV2x/3x..= 11 (NC inverted error)
Set value = LMV5x / ETAMATIC = 11 (NC inverted error)
Set value = 10 (NO error)
