Wiring the GRAFIK Eye QS with EcoSystem Control Unit

Powering More Than 3 Wallstations Example

The GRAFIK Eye QS with EcoSystem control unit can power up to 3 seeTouch wallstations. An external 24 V- power supply is
required to power more than 3 wallstations.
• The +24 VDC wire from the power supply
connects to QS link terminal 2 on all of
the wallstations it is powering. This wire
does not connect to terminal 2 on the
GRAFIK Eye QS control unit.
