FOCKE MELER GLUING SOLUTIONS INSTALLATION
3-10
3. Insert the wires in XP11 and XP12 terminal blocks and tighten them
with the fixing screws. The terminal block is double so you must
to connect every wire in a free hole of the terminal block. It has no
polarity so it doesn’t matter the place you connect them.
4. Make sure that the cables are firmly attached by the terminal screws.
5. For the signal to work, external mode on the control panel must be on.
Motor speed set point reference
1. If only this signal will be connected, use a 0.5 mm
2
two-wire cable.
2. Open the door of the electrical cabinet as far as possible. Thread the
power cord (Ø4-8 mm) through the electrical cable gland Pg13, making
sure that the cord reaches the terminal blocks where that signal has to
be connected.
3. Insert the wires in XV11 and XV12 terminal blocks and tighten them
with the fixing screws. This is a double terminal, which makes it
necesarry to connect each wire in one of the holes in the terminal. The
positive signal wire must be connected to XV12, while the negative wire
must be connected to XV11.
4. Make sure that the cable is well connected and that its path through
the electrical cabinet presents no risks of snagging, being cut or any
other accidental deterioration.
5. For the signal to work, external mode on the control panel must be on.
Failures output in the inverter
1. If this is the only signal being connected, use 0.5 mm
2
two-wire cable.
Install an electrical wall bushing Pg13 next to the electrical supply
input.
2. Thread the power cord (max. Ø12.5 mm) through the electrical wall
bushing Pg13 and fasten it to the inside anchor, making sure that the
cord reaches the power card connector.
3. Connect the two wires from the start-up signal to the terminals XE11
and XE12. This is a double terminal, which makes it necessary to
connect each wire in one of the two holes in the terminal. Since this
contact is not under voltage, there is no connection polarity.
4. Make sure that the cables are firmly attached by the terminal screws.
Warning: It must be connected to 24 AC or DC voltage with a maximum
current of 1A.
