6.2 Design of product
• X-Care device is available on all Helix pumps.
• It detects abnormal operations like dry running or
remaining air at the top of the pump that could
lead to mechanical seal failure.
• One dry contact relay allows defect monitoring if
selected. When it is wired to a supply contactor
that could protect pump in an effective way.
• Communication features allow status and data
exchange to supervisory control system.

6.2 Relay operations
• X-Care is equipped with one dry contact relay in
order to prevent any defect occurrence. To pro-
tect pump efficiently, it must be wired to pump
power supply.
• Relay could be set as ‘normally opened mode or
‘normally closed’ mode depending on the
cabling.
• Every defect has got a maximum number of
occurrences per day, starting from X-Care power
on (see chapter 10 faults, causes and remedies).
Once this maximum number is reached, relay
stays blocked until any involved adjustment to
keep it re-active again (see chapter 10 faults,
causes and remedies).
