4.7.1
Input Terminal 7 - Test/Reset/MULTI SOFT STOP
Input from a N.O. contact
– the functions described above are selected from the keypad (refer to section
7.8.7 page 73) or software commands sent via the communication protocol (Modbus, Profibus or DeviceNet).
When RESET function is selected
- connect terminal 7 using a N.O. momentary contact, to control input
voltage to reset the HRVS-DN.
When TEST function is selected
- connect terminal 7 to control input voltage (use a N.O. contact) to conduct
a firing test to the HRVS-DN. For more details on the firing test refer to section
14.3 page 121.
When MULTI SOFT STOP optional function is selected
- connect terminal 7 to control input voltage (use a
N.O. contact) to operate the soft starter in a Multi Soft Stop procedure.
For wiring diagram refer to section
5.12 page 37.
For programming refer to section
7.8.7 page 73.
4.7.2
Input Terminal 8 - Dual Adjust/Reset
Input from a N.O. contact
- selection between above functions is made from the keypad (refer to section
7.8.7 page 73) or through the communication (Modbus, Profibus or DeviceNet).
When DUAL ADJUSTMENT function is selected
- connect terminal 8 to Control Input voltage to operate the
HRVS-DN with the DUAL ADJUSTMENT characteristic. DUAL ADJUSTMENT characteristic is programmed
as explained in section
7.8.5 page 70. You can switch between the primary and DUAL ADJUSTMENT
settings before and/or during starting.
When RESET function is selected
- connect terminal 8 to Control Input voltage (use a N.O. momentary
contact) to reset the HRVS-DN.
For wiring diagram refer to section
5.9 page 34.
For programming refer to section
7.8.7 page 73.
4.7.3
Output Terminals 10, 11 & 12 – Immediate/# Strts PreAlarm
Programmable functions (refer to section
7.8.7 page 73):
IMMEDIATE (after start signal)
- when immediate is selected, the relay is energized upon the START signal.
The relay is de-energized when one of the following occurs:
Fault
Control Supply outage
STOP signal
When SOFT STOP is operated
- the relay is de-energized at the end of the SOFT STOP process.
The relay incorporates on and off delays of 0-3600 sec. each.
The immediate relay can be used for the following purposes:
Interlock with other systems
Signalling
Delay the opening of a Line Contactor at the end of SOFT STOP, thus allowing current to decrease to zero
before opening the contactor
Switch to / from Dual Adjustment settings with a time delay from the START signal (see Special Starting
section
13.5.3.1 page 117).
# Strts PreAlarm detection
- When configured to # STRTS PREALARM the relay is energized if a start
command will cause the soft starter to trip on TOO MANY STARTS.
