Error outputs with contacts and binary output circuits
(iii)
Automatic supervision function drives a contact of the power supply module (PWS)† when an
error occurs without warning; additionally, binary output circuits (BOs‡) will be locked out to
drive when serious error (Level 1=Critical error) is detected.

Error output by PWS contact†
If serious error (Level1) is detected by Automatic supervision function, normally-closed-contact
(N/C) on FAIL1 and FAIL2 terminals is closed. On the other hand, the N/O contact is open on
the serious error, as shown in Table 9.1-4.
Locking out of BO circuit operation‡
BO is locked out to operate, when serious error (Level1) occurs. Serious error stops trip signal
generations to the BO circuit. When serious error is removed, the operation will be recovered.

Affection of application operation by error levels
(iv)
The error levels influence the operation of relays and general control functions.
