GENERAL SAFETY
Recommendation(s)
Press the On/Off button to cycle power
Confirm all connections are securely fastened and that no mechanical
damage to wiring has occurred
Re-connect wiring and thread together tightly
Reverse wiring if found to be incorrect
[Warning: Control module boards manufactured prior to 2010 may not
be equipped with reverse polarity protection and if powered in a reverse
condition will require replacement]
Remove fuse holder cap and inspect fuse for damage Replace if required
[0 25 x 1 25" - 2 5A]
Confirm 24V DC power supply is available to the control module with a
volt meter Replace or repair power supply as required
If the System is running off a DC battery bank it is recommended to dis-
[
connect the charging source [
low
to ensure accurate results
Confirm charge regulator is outputting 24-28V If your charge regulator
is equipped with a low voltage disconnect make sure to test its function-
ality and set points
If your pump is equipped with the optional 4-20 mA analog input it will
override manual entries when in remote mode Disconnecting the 4-20
mA input cable will resume normal manual operation
Confirm 24V power supply is available to the control module with a volt
meter
If the System is running off a DC battery bank it is recommended to dis-
connect the charging source [
to ensure accurate results
This condition can cause damage to the Systems drive if left for ex-
tended periods. If after identifying and correcting a voltage prob-
lem and the drive is still found to chatter it is recommended to send
the System in for inspection as motor bearings may be damaged
If any valves are found to be closed and if safe to do so, open valves
MCI offers many drive options that require specific controllers Before
installing a new pump controller please contact MCI customer service:
+1 250 888 4565 to confirm compatibility Please provide the Systems
model and serial number to confirm compatibility
Please confirm your pumps maximum output pressure rating This can
be found under the 'Specifications' section of this manual It is very im-
portant this pressure not be exceeded It is unsafe and will cause pre-
mature System failure
