Protection
Overload
This parameter is used to protect the ASD from an over-current condition. The
standard overload rating of the
Q9 Plus ASD
is 120% operation for 60 seconds.
This setting allows for the overload protection to be switched from the standard
overload detection means (Thermal Detection and Overload) to thermal
detection only.
Settings:
0 — Temperature (Thermal Detection) + Overload
1 — Temperature (Thermal Detection) Only
The
Thermal Detection Only
selection is used when multiple devices are
installed horizontally as described on
pg. 14
.

Terminal
Input Special Functions
This parameter is enabled by providing a non-zero value here. This function
monitors the
V/I
input signal and if the
V/I
input signal falls below the level
specified here and remains there for a period in excess of 0.3 seconds a trip will
be incurred (E-18).
This value is entered as 0% to 100% of the
V/I
input signal range.

Special Parameters
This parameter is used in conjunction with a discrete output terminal setting to
notify the operator of the remaining useful life of critical components of the
ASD system.
With a discrete output terminal set to
Part Replacement Alarm
(see
Table 13
on pg. 239
) and the calculation derived from the parameter setting, maintenance
scheduling may be enhanced.
Settings:
1 — Under 10° C (50° F)
2 — Under 20° C (68° F)
3 — Under 30° C (86° F)
4 — Under 40° C (104° F)
5 — Under 50° C (122° F)

Special Parameters
At system startup, this parameter sets a time-delay for the start of the
Rush
Relay
activation in an attempt to allow the DC bus voltage to reach the normal
operating level before outputting a signal to the motor.
