6. Troubleshooting
ERROR
CODE
SOLUTION
EYA
(HIGH
CURRENT
ERROR)
• Before the checks, if the relay is receiving 'start' command, first stop this command by turning
the 'start' inlet into an open circuit.
• Ensure there is no electrical or mechanical failure in the pump or the electric motor before
taking any measurement and action.
• Check the firmness of cables and terminal connections.
• Refer to error history to understand the cause of the error. Enter the password screen by
pressing the 'Set' button, enter the password using the 'Up/Down' buttons and check the error
history in the PAG program.
• Manually test the current drawn by the motor, check the current with an ammeter and compare
this value with the value displayed on the screen. Compare all currents drawn from all phases.
• After troubleshooting the failure which caused the high current error, reset EYA error by
pressing and holding 'Up/Down' buttons.
• Ensure that the system is operating properly after troubleshooting and resend start command
through the 'start' input
EDA
(LOW
CURRENT
ERROR)
• Before the checks, if the relay is receiving 'start' command, first stop this command by turning
the 'start' inlet into an open circuit.
• Ensure there is no electrical or mechanical failure in the pump or the electric motor before
taking any measurement and action.
• Check the firmness of cables and terminal connections.
• Ensure the suction/delivery valves are open in the pump system, and there is water in the
suction line and no air in the system.
• Refer to error history to understand the cause of the error. Enter the password screen by
pressing the 'Set' button, enter the password using the 'Up/Down' buttons and check the error
history in the PAG program.
• Manually test the current drawn by the motor, check the current with an ammeter and compare
this value with the value displayed on the screen. Compare all currents drawn from all phases.
• After troubleshooting the failure which caused the low current error, reset EDA error by
pressing and holding 'Up/Down' buttons.
• Ensure that the system is operating properly after troubleshooting and resend start command
through the 'start' input
ESS
(NUMBER
OF SWITCH-
ES ERROR)
• ESS error is triggered when the maximum number of switches allowed per hour set in the
PSS program is exceeded.
• Check the value set in PSS program.
• This error will be reset and deleted at the end of the period defined based on the value set
in PSS.
• Press and hold 'Up/Down' buttons simultaneously if manual reset is required after
troubleshooting.
EBL
(BLOCKED)
• EbL error is triggered at the end of the automatic reset trial count defined in PYr and Pdr
programs.
• Before the checks, if the relay is receiving 'start' command, first stop this command by
turning the 'start' inlet into an open circuit.
• Ensure there is no electrical or mechanical failure in the pump or the electric motor before
taking any measurement and action.
• Identify the reason for EdA (low current) or EYA (high current) error.
• Follow the steps in the EdA (low current) and EYA (high current) troubleshooting sections
and identify the reason for the EdA or EYA error.
• Press and hold 'Up/Down' buttons simultaneously to reset the EbL (blocked) error manually
after troubleshooting.
• Ensure that the system is operating properly after troubleshooting and resend start
command through the 'start' input
