Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Log incoming voltage during a start and check condenser cleanliness.
When to call us
Repeated over-current trips need a power quality assessment — call us before the drive is damaged.
Likely causes
What to check
Check cable screening and confirm the address DIP settings match the commissioning record.
When to call us
Call us if resetting doesn't hold — intermittent comms usually means noise or a marginal cable run.
Likely causes
What to check
Compare chilled water delta-T to the commissioning figure across a full load cycle.
When to call us
Book a diagnostic visit — absorption capacity loss is progressive and cheaper to fix early.
