Problem What To Do
HRVS-DN Control
Module is not
powered after external
control voltage is
connected.
 Verify that cabinet MCBs are set to ON position.
 Verify that the Emergency Stop push button is released.
 Verify that customer terminals 5 & 6 are jumpered.
 Verify that the DOL/Soft Start selector switch is set to Soft Start.
 Verify that rated control voltage is connected to customer terminals 1 & 2.
 Verify correct polarity for DC control voltage.
Upon control voltage
connection the HRVS-
DN Control Module
trips immediately
 Disconnecting control voltage from the Control Module and reconnecting the
control voltage does not reset the soft starter if tripped.
 Reset the HRVS-DN by pressing the Reset key.
PWR ON & NO STRT
Trip occurs before
starting.
 It occurs, when mains voltage is connected to the HRVS-DN more than 30
sec. without a start signal.
 It may occur if mains voltage is connected downstream (“below”) from the
Line Contactor instead of upstream (“above”) the Line Contactor. The starter
protects itself from overheating.
 Can be disabled for special applications.
Local start command
does not cause any
action.
 Verify that the Local/Remote/Off Selector switch is set to Local and remote
light does not light.
 Verify that the Fault light is not active on the front panel, or on the starter
control panel or on the MPR panel.
 If the Fault light is turned ON:
o Verify that there are no fault messages on HRVS-DN & MPR displays.
o Reset if necessary.
o Check setting of the trip relay logic (FAULT/FAULT FAIL-SAFE) of the
soft starter and MPR. Improper setting de-energizes fault relays FT &
FT/1.
Remote start
command does not
cause any action.
 Verify that the Local/Remote/Off Selector switch is set to Remote and the
Remote indication light is on.
 Verify that the Fault indication light is not active on the door and starter &
MPR panels.
 If the trip indication light is turned ON:
o Verify that there are no fault messages on the Starter & MPR displays.
o Reset if necessary.
o Check setting of the trip relay logic (FAULT/FAULT FAIL-SAFE) of the
soft starter and MPR. Improper setting de-energizes fault relays FT &
FT/1.
