• 7 Relay Outputs
7A – Relay A Function
Options:
Off
Relay A is not used.
Main Contactor (default)
The relay closes when the LV-DS receives a start command,
and remains closed as long as the motor is receiving
voltage.
Run
The relay closes when the starter changes to run state.
Trip
The relay closes when the starter trips (see parameter 16A
to 16M).
Warning
The relay closes when the starter issues a warning (see
parameter 16A to 16M).
Low Current Flag
The relay closes when the low current flag activates (see
parameter 7J Low Current Flag, while the motor is running).
High Current Flag
The relay closes when the high current flag activates (see
parameter 7K High Current Flag, while the motor is running).
Motor Temperature Flag
The relay closes when the motor temperature flag activates
(see parameter 7L Motor Temperature Flag).
Description: Selects the function of Relay A (normally open).
7B, 7C – Relay A Delays
The LV-DS can be configured to wait before opening or closing Relay A.
Parameter 7B Relay A On Delay
Range: 0:00 - 5:00 (minutes:seconds) Default: 0 second
Description: Sets the delay for closing Relay A.
Parameter 7C Relay A Off Delay
Range: 0:00 - 5:00 (minutes:seconds) Default: 0 second
Description: Sets the delay for re-opening Relay A.
7D~7I – Output Relays B & C
Parameters 7D~7I configure the operation of Relays B and C in the same way as parameters 7A~7C
configure Relay A. See Relay A for details.
Relay B is a changeover relay.
• 7D Relay B Function Default: Run
• 7E Relay B On Delay
• 7F Relay B Off Delay
Relay C is normally open.
• 7G Relay C Function Default: Trip
• 7H Relay C On Delay
• 7I Relay C Off Delay
7J, 7K – Low Current Flag and High Current Flag
The LV-DS has low and high current flags to give early warning of abnormal operation. The current
flags can be configured to indicate an abnormal current level during operation, between the normal
operating level and the undercurrent or instantaneous overcurrent trip levels. The flags can signal the
situation to external equipment via one of the programmable outputs.
The flags clear when the current returns within the normal operating range by 10% of the programmed
flag value.
Parameter 7J Low Current Flag
Range: 1% - 100% FLC Default: 50%
Description: Sets the level at which the low current flag operates, as a percentage of motor full
load current.
Parameter 7K High Current Flag
Range: 50% - 600% FLC Default: 100%
Description: Sets the level at which the high current flag operates, as a percentage of motor full
load current.
7L – Motor Temperature Flag
The LV-DS has a motor temperature flag to give early warning of abnormal operation. The flag can
indicate that the motor is operating above its normal operating temperature but lower than the overload
limit. The flag can signal the situation to external equipment via one of the programmable outputs.
Range: 0% - 160% Default: 80%
Description: Sets the level at which the motor temperature flag operates, as a percentage of the
motor's thermal capacity.
