Powering More Than 3 Wallstations Example
• 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.
The GRAFIK Eye
®
QS control unit can power up to 3 seeTouch
®
wallstations. An external 24 V
-
power supply is required to power
more than 3 wallstations.
To power source
QSPS-P1-1-50
(powers up to 8 seeTouch
