Table “FIRE MODE + CO with NC activation signal”
6.2 WIRING
Before the start of the programming, wire the L1-L2-L3 input phases when using three phase equipment and wire the
L1-L2/N input phases when using single phase equipment.
Once the “FIRE MODE with NC contact + CO” or “FIRE MODE with NO contact + CO” control mode is selected, that
is after introducing the parameters of the fire mode table (section 6.1), wire the drive as seen in the picture. (See Fig. 7
or 8.)
The Fire signal disables the protection features and maintains a constant speed. The CO mode activates a constant
speed, distinct from the Fire speed. Both modes require a starting switch (Run), which can be replaced by a short-circuit
between terminals 1 & 2, or a contact related to the Fire and Normal mode activation.
In case the short-circuit is chosen, the drive will be always enabled and only will stop when the short-circuit is opened;
then display will show .
6.3 “FIRE MODE + CO with preset speeds” OPERATION MODE
Fire Mode with NO activation signal
1. Verify that the Fire mode signal triggers the Fire mode as well as the start signal (Run).If necessary use a two
contact Normally Open relay.
2. Verify that the CO mode signal triggers the CO mode as well as the start signal (Run).If necessary use a two contact
Normally Open relay.
3. When one of the two signal is active, the drive will accelerate towards de preset speed according to the normally
open contact table (see section 6.1).
4. When the two signals aren’t active, the drive will start to decelerate and stop, showing in the display.
5. The Fire signal disables the protection features so the drive will maintain continuous operation in emergency
conditions. The speed can be forward or reverse depending on the value set in the “Fire Speed” parameter.
