AF6ZP0CA – COMBIAC0 & ACE0 2uC – User Manual
-
If the problem is still present after replacing the encoder, the failure is in
the controller.
EPS RELAY OPEN
(MDI/LED code = 70)
Cause:
The controller receives from EPS information about the safety contacts being
open.
Troubleshooting:
Verify the EPS functionality.
EVP COIL OPEN
(MDI/LED code = 9)
Cause:
No load is connected between the EVP output (
A24
) and the electrovalve
positive terminal.
Troubleshooting:
-
Check the EVP condition.
-
Check the EVP wiring.
-
If the problem is not solved, replace the logic board.
-
EVP DRIVER OPEN
(MDI/LED code = 9)
Cause:
The EVP driver is not able to drive the EVP coil. The device itself or its
driving circuit is damaged.
Troubleshooting:
This fault is not related to external components. Replace the logic board.
EVP DRIV. SHORT.
(MDI/LED code = 9)
Cause
-
The EVP driver (output
A24
) is shorted.
-
The microcontroller detects a mismatch between the valve set-point and
the feedback of the EVP output.
Troubleshooting
-
Check if there is a short circuit or a low-impedance conduction path
between the negative of the coil and -B.
-
Collect information about:
o
the voltage applied across the EVP coil,
o
the current in the coil,
o
features of the coil.
Ask for assistance to Zapi in order to verify that the software diagnoses are
in accordance with the type of coil employed.
If the problem is not solved, it could be necessary to replace the controller.
EVP2 COIL OPEN
(MDI/LED code = 10)
Cause:
No load is connected between the EVP2 output (
A23
) and the electrovalve
positive terminal.
Troubleshooting:
-
Check the EVP2 condition.
-
Check the EVP2 wiring.
