Switching on the unit
1. Turn on the PFL22M1500 by pulling out the yellow Emergency Stop button
(item 8) which also acts as an on/off switch. At turn-on all lamps will
illuminate for a short period of time, during self test.
Note: The Voltage and Mode selector switches are locked in position during
transportation to help avoid miss-handling. Therefore they cannot be
moved or turned until the unit is turned on. Additionally once a mode
has been selected these switches are locked.
2. Assuming all interlocks are satisfied the Status Bar (item 1) will glow “Green”
and all Interlock lamps will remain off. If any of the interlocks are not
satisfied the lamps will glow yellow.
Test Procedures
D.C. Dielectric withstand (Proof) Test
The PFL22M1500 generates a dc test voltage of 0 to 20 kV negative wrt to
Earth/Ground with a current of 0 to 115 mA (10kV range) and is used to test
the integrity of cable installations. The test voltage is defined by the user and
local regulations.
1. Set the rotary Voltage Control knob (item 21) to the “Zero Start” (item 9)
position.
Note: Range and function switch cannot be moved if a mode is active.
2. Set the Voltage Range switch (item 20) to the desired range either 10 or
20kV. At this stage the Status Bar (item 1) will glow “Red”
3. Set the Mode (Filter) selector switch (item 19) to Proof-Burn & Surge. Both
lamps will illuminate, advising that either of these modes are available.
4. Depress the pushbutton of the desired mode, in this case Proof/Burn.
Selection is confirmed by the pushbutton remaining illuminated and other
pushbutton extinguishing.
Initiate button Illuminates.
5. The required test voltage is set by using the Voltage Control knob (item 21).
This voltage is displayed on the d.c KiloVolt meter (item 13) and the voltage
Preview Lamp (item 7) is illuminated indicating that the displayed voltage is a
“preview only” with no HV being applied at this time.
