6.2.1 MOTOR
PATH: ACTUAL VALUES  STATUS  MOTOR
The MOTOR STATUS value reflects operating state of the motor. The MOTOR THERMAL CAPACITY USED represents the thermal
model accumulated thermal capacity used as a percentage value. The ESTIMATED TRIP TIME ON OVERLOAD value repre-
sents the estimated time to trip (in seconds) from the thermal model assuming that the motor current remains at its current
level. It is obtained from the thermal model curve and takes into account that some percent of the thermal capacity has
already been used.
The
THERMAL LOCKOUT TIME reflects the calculated time required for the thermal capacity used to decay from its current
value to the level when thermal start inhibit is removed and new motor start is permitted. The THERMAL LOCKOUT TIME value
is displayed only when motor is offline. For details of lockout time calculations see the Thermal Model section of Chapter 5.
The
START/HOUR LOCKOUT TIME, TIME-BTWN-STARTS LO TIME, and RESTART DELAY LO TIME lockout time values are calcu-
lated from the Maximum Starting Rate, Time Between Starts, and Restart Delay elements, respectively. The
TOTAL MOTOR
LOCKOUT TIME
value is calculated as the maximum of all lockout times shown in this menu.
6.2.2 CONTACT INPUTS
PATH: ACTUAL VALUES  STATUS  CONTACT INPUTS
The present status of the contact inputs is shown here. The first line of a message display indicates the ID of the contact
input. For example, ‘Cont Ip 1’ refers to the contact input in terms of the default name-array index. The second line of the
display indicates the logic state of the contact input.
