Acknowledging errors and clearing the malfunction list
To change the valve status (valve state) from "0 (not ready) to"1" (configurable), the error must be
acknowledged once the cause has been remedied.
1.
End transfer mode by setting the transfer control (PDO byte 1, bits 7 … 5) to a value of "3". The
valve switches to mode (valve mode) 61, valve status (valve state) is "error" (value 3).
2. Remedy cause of error. Status of the valve changes to “not ready” (value 0).
3. Set operating mode of valve (valve mode, PDO byte 0, bits 5 … 0) to the value "62" ("acknowledge
error"). Status of the valve changes to "ready" (value 1).
Acknowledgment deletes all entries in the malfunction list for this valve slot.
If the malfunction list of a valve slot contains accumulated entries of the "Warning" type but no active
or inactive errors, the malfunction list can also be in the status (valve state) "1" (configurable) by reset
of the operating mode to "62".
Acknowledgement of errors without previous read-out of malfunction list
If the error can be cleared without a read-out of the malfunction list (and hence without using transfer
mode), the following simplified procedure results:
1.
An error is present: PDI byte 0, bit 7 = 1 and bit 6 = 1.
Ä
valve state = failure
2.
The cause of the error has been remedied: PDI byte 0, bit 7 = 0 and bit 6 = 0.
Ä
valve state = not ready
3.
The error is acknowledged: set PDO byte 0, bit 5 … 0 "valve mode" to the value 111110
2
= 62
