5.2 Supplying power to the HFG01

Figure 2: HFG01 power supply

The HFG01 is powered by an external 24 Vdc power supply unit which connects
to the input socket on the front panel

. Pressing the power switch

with the

24 Vdc unit connected will turn the HFG01 on, which will be confirmed by the
green indicator

. Pressing the power switch again will turn the HFG01 off.

5.3 Operating modes

Figure 3: HFG01 mode selection

The operating mode is selected using the Test Mode switch

. The operation of

each test mode is described in Table 1 below. Note that if the Test Mode switch is
changed whilst a test is running, the test is automatically disabled.
