4-8 Troubleshooting
CntactrCflct
➁
Contactor input functions are in conflict:
• When Par 1391
[ContactorControl] is set to “None”, both relay outputs
(Pars 1392
[Relay Out 1 Sel] and 629 [Relay Out 2 Sel] and all digital inputs
([Digital Inx Sel]) cannot be set to “Contactor” or “ContactorDB”.
• With [ContactorControl] set to “Contactor”, one relay output and one digital
input must be set to “Contactor”. No output can be defined as
“ContactorDB”.
• With [ContactorControl] set to “Contactor+DB”, both relay outputs and one
digital input must be set to “Contactor”, “ContactorDB” and “Contactor”,
respectively.
Because any relay output can be configured as contactor or DB control and
any digital input as contactor status, care must be taken to correctly wire the
terminal blocks to match the parameter selections.
