Test procedure (External valve amplifier)
In this menu the analogue output for valve control is tested.
Figure 5.c
1. Move the cursor to the field ‘left valve’.
2. Use the manual movement keys to put both the output value and the offset value at zero.
The voltage at the output should now also be zero.
3. If the measured output voltage is not zero, you must set the output voltage to zero with
the offset adjustment.
4. Repeat these steps for the other valve.
5. Further fine-tuning can be done through the calibration procedure as described in the
Delem machine parameter manual at parameter 15, ‘Calibrate valves’. That procedure is
designed especially for external valve amplifiers.
Failure
External electronics, wiring, valves or DA-52s.
