Parameter Descriptions
INITIAL DELAY 2
PREF: 93.07
Default: —.x s
Range: 0.0 to 600.0 s
Determines the delay for the first restart attempt when the trip is included in TRIGGER 2.
The delay is measured from all error conditions clearing.
ATTEMPT DELAY 2
PREF: 93.08
Default: —.x s
Range: 0.0 to 600.0 s
Determines the delay between restart attempts for a trip included in TRIGGER 2. The delay is measured from all error
conditions clearing.
TRIGGER 2 WORD 1 to
TRIGGER 2 WORD 6
PREF: 93.09, 93.10, 93.17,
93.18
, 93.21, 93.22
Default: 0000
Range:0x0000 to 0xFFFF
Allows Auto Restart to be enabled for a selection of trip conditions.
If a trip is included in both TRIGGER 1
WORD 1 and TRIGGERS WORD 1 for instance, then the times associated with
TRIGGER 1
WORD 1 will take priority.
Refer to page
D-183: “Hexadecimal Representation of Trips” for an explanation of the four-digit codes.
PENDING
PREF: 93.11
Default: FALSE
Range: FALSE / TRUE
Indicates that an auto restart will occur after the programmed delay.
RESTARTING
PREF: 93.12
Default: FALSE
Range: FALSE / TRUE
Indicates that an auto restart is occurring. TRUE for a single block diagram execution cycle.
ATTEMPTS LEFT
PREF: 93.13
Default: 5
Range: —.
Indicates the number of attempts left before an external fault reset is required.
TIME LEFT
PREF: 93.14
Default: —.x s
Range: —.x s
When in the Restarting state, this parameter indicates the time left before an auto restart attempt will be permitted. When non-
zero, this value is un
affected by changes to ATTEMPT DELAY 1.
