H9 ASD Installation and Operation Manual 189
V/I Analog Input Broken Wire Detection Level
Program Termi na l 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 of 0.3 seconds or more a trip will
be incurred (E-18).
This value is entered as 0% to 100% of the V/I input signal range.
Direct Access Number — F633
Parameter Type — Numerical
Factory Default — 0 (Disabled)
Changeable During Run — No
Minimum — 1
Maximum — 100
Units — %
Annual Average Ambient Temperature
Program Special 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 8 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)
6 — Under 60° C (140° F)
Direct Access Number — F634
Parameter Type — Selection List
Factory Default — Under 30°
Changeable During Run — No
Rush Relay Current Activation Time
Program Special Special Parameters Rush Relay Current
Activation Time
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.
Direct Access Number — F635
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — No
Minimum — 0.0
Maximum — 2.5
Units — Seconds
PTC1 Thermal Selection
Program Special Special Parameters PTC1 Thermal Selection
This parameter Enables/Disables the optional external thermal detection circuit
of the Expansion IO Card Option 1. A thermistor is connected from TH1+ to
TH1- of TB3 on the Expansion IO Card Option 1.
Should the thermistor resistance reading fall below 50 because of an over-
temperature condition or exceed 3000 because of an open circuit an External
Thermal Fault (OH2) will be incurred.
Note: While this parameter is Enabled, the system cannot be restarted
until the thermistor value recovers to the level of 1.8 k from an
over-temperature condition. An Auto-Restart will not be
initiated subsequent to an External Thermal Trip (OH2). A
manual restart will be required in the event of an OH2 trip.
Settings:
0 — Disabled
1 — Detect Disconnect
Direct Access Number — F637
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
