6. A 2-pin connector marked Back Inlet for the connection of the solenoid valves for the
back PTV/PTVBKF cryogenic system.
7. A 2-pin connector marked Front Inlet for the connection of the solenoid valves for the
front PTV/PTVBKF cryogenic system.
8. A 2-pin connector marked Oven for the connection of the solenoid valves for the Oven
cryogenic system.
Four protecting fuses are present inside the module. See
Table 20. Aux Temperature/Cryo Module Protecting Fuses
Fuse Type
F1 F2A 250V; (5 x 20 mm)
F2 F2A 250V; (5 x 20 mm)
F3 T2A 250V; (5 x 20 mm)
F4 F1.6A 250V; (5 x 20 mm)
The module features the following:
• The valve control of the Oven cryo option.
• The valve control of the front/back PTV cryo option.
• Sixty-three timed events to automatically drive up to eight external on/off solenoid valves.
The module should be installed into a free external module housing provided on the back of
the GC. See Figure 476.
