Error Codes
Error codes may be displayed by the PP600. These are shown as “E nn”, where
nn gives the number of the error. To cancel the error message, press
“SELECT”. The error codes are:
EC 1, EC 2
The current to one of the outputs has been turned off because the
maximum output energy has been exceeded. To fix this, reduce the pulse
width or increase the maximum output energy allowed.
Et
(introduced in firmware revision 017)
The PP600 has a thermal cutout. If the internal temperature reaches 62
o
c,
which corresponds to a case temperature of approximately 70
o
c, the
output currents are turned off. This message will persist until the PP600
has cooled down below 62
o
c.
E 16
When the unit has powered up the non-volatile memory was corrupt and
has been cleared. Set up the unit again.
E 25, E 26
The PP600 is calibrated during manufacture. This stored calibration has
become invalid. Make a note of the number and contact your distributor.
E 00, E 01, E 02, E 03, E 04, E 05, E 06, E 07, E 18, E 42, E 43
A hardware error has occurred. Try power cycling the unit and trying
again to see if the fault clears. If not, make a note of the number and
contact your distributor.
E 33, E 44, E 49, E51
A serial command has been received which is invalid. E 33 is generated if
the command format is wrong and the other messages if a parameter has
an illegal value. Correct the command and re-send it. If these errors are
intermittent then check the integrity of the serial link.
Note that these error messages are also output on the serial port but the
number is sent in hexadecimal, so the four errors are sent as “E21”,
“E2C”, “E31” and “E33” respectively.
E 17, E 40, E 41, E 64, E 65, E 67, E 74
An internal software error has occurred. Make a note of the number and
contact your distributor.
