Maintenance
The BR400 Booster Relays do not require any routine maintenance. If a contaminated air supply has been used,
then there may be need to clean the filters or disassemble the relay to clean the supply and exhaust seats and
valves.
Troubleshooting
If the output pressure does not respond to changes in the input pressure, check that supply pressure is at proper
value and that signal and supply filters are not plugged with foreign matter. Check also that supply and exhaust
valve seats are clean.
If output pressure is not stable or is slow to respond, check setting of bypass needle valve. See bypass valve
setting procedure under "Operation".
