Dionex RFC Features
2.1
Overview of Device Control
The Dionex RFC can provide power to a device (suppressor, EGC, or
CR-TC) only when the pump flow is on. A TTL or AC connection
between the Dionex RFC and the pump or DX-120 signals the Dionex
RFC when the pump flow is on. When this occurs, the
RFC ENABLED
LED on the front panel (see Figure 2) turns on, indicating the Dionex
RFC is ready to control devices.
The
DEVICE SELECT
buttons turn on or off control of individual devices.
Power is supplied to a device only when
RFC ENABLED
is on and the
DEVICE SELECT
LED for the device is on. Figure 1 illustrates the
relationship between the Device Select and RFC Enabled functions.
Figure 1. Summary of Dionex RFC Enabled and Device Select Functions
When priming the pump, turn off all devices (suppressor, EGC, and
CR-TC). During priming, the pump is on and the Dionex RFC is
enabled, but there is no flow to the devices.
