Power Requirements and Voltage Selection
Valve ovens installed by the factory will contain the line voltage selected as noted
by the sales order, 115 V ac or 230 V ac. The line voltage selection can be
changed by relocating a jumper located behind the valve driver electronics (Figure
1-3).
CAUTION AC line voltage is applied to the valve oven when the main GC is turned on. Turn the
main GC power off before removing the valve oven heaters.
Valve oven power for the 24 V dc solenoid is supplied by an external power
module that plugs into the rear of the valve oven. This power module will accept
input voltage from 106 V ac to 240 V ac. A green light on the front of the valve
oven (Power On Indicator) indicates when the power module is plugged in
(Figure 1-2).
NOTE In case of using the TRACE GC Ultra Valve Box for up two valves, any power supply is
necessary since the solenoid valves are activated directly by the TRACE GC Ultra.
