This chapter describes how the Human-machine interface
(keypad and display) works. For detailed description of
each function, see chapter 7 Functions.
6.1 Navigation Overview
The Human-machine interface, HMI is used for several
purposes such as programming the softstarter, e.g.
setup of inputs and outputs, protections, warnings, and
communications. The HMI is also used for monitoring,
local control and status information of the softstarter. See
Figure 44.
The HMI contains of:
• Display
• Selection and Navigation keys
• Mini USB port
• LED status indicators
6.1.1 LED indicators
The LED status indicators work as in Table 1 LED status:
Table 1 LED status
LED Color Description
Ready
1
Green • Off: When control supply voltage U
s
is
off or unconnected.
• Flashing light: When control supply
voltage U
s
is On and operational voltage
U
e
is Off.
• Steady light: When control supply volt-
age U
s
is On, and operational voltage
U
e
is On.
Run
2
Green • Off: When the motor is not running.
• Flashing light: When softstarter is
controlling operational voltage U
e
during
start or stop ramp.
• Steady light: When full operational volt-
age U
e
is on at Top of Ramp.
Protection
3
Yellow • Off: When the softstarter has not tripped
on any protection
• Flashing light: The protection has
tripped and reset is possible.
• Steady light: The protection has tripped
and reset is not possible.
Fault
4
Red • Off: When the softstarter has not tripped
on any fault
• Flashing light: Fault has occurred and
reset is possible.
• Steady light: Fault has occurred and
reset is not possible.
See Figure. 45: LED status.
When fault or protection LED is activated, the display will show the
actual fault or protection as an event code and an indication text. Press
information-key for further information.
See chapter 10 Troubleshooting for description of fault, protections
and warnings.
