10.2.28 Supervision of power supply module (Power error)
A power error is issued when the DC voltage generated in the power supply module (PWS†) is
less than a threshold voltage. Thresholds for issuing the power error are determined by
inserting a shunt connector on the PWS.
†Note: For more information about the PWS, see Chapter Technical description, Power
supply module . When the AC supply—however, the manufacture does not
guarantee the operation in the AC power—is connected with the PWS module, the
user shall set Off for the setting [CHK_POWER:Sw] (that is, the supervision
function concerning to the PWS module are stopped). Remember that the state of
the binary input circuit (BI) will be latched when the Power error occurs anytime.
(i) Error level

using setting [CHK_POWER:LVl]. Set On for the setting [CHK_POWER:Sw]. The
manufacturer sets one (1) second to detect the failure, and it is reset with in a second when the
failure is cleared.
(ii) Error message
