MCS – MicroMag Error / Alarm Manual
Version: 02/21/2020
This state is entered whenever a critical situation
is encountered that could cause harm to the chiller.
In this state, all Relay Outputs except the alarm are
turned off and will read “LOCKOUT.”
Lockouts can be reset from the keypad or with the
MCS-Connect program; however, if the lockout
condition has not been corrected, the system will
again be forced into this state.
Note - If the Lockout Reset is used more than 6
times in one day, the unit cannot be reset except
with Factory authorization. Call Drake for support.
This state is entered when all compressors have
been shut down, either due to normal operating
conditions or due to a lockout, and only the chilled
fluid pump is running.
