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.
