** Modification to the K3 common alarm relay on the
microprocessor controls of the Environmental unit is necessary
to enable remote on/off �� this modification will necessarily
eliminate the common alarm relay output. Refer to the
Installation / Operations Manual of the Environmental unit, or
consult Liebert Environmental Support.
Note that if the high/low temperature and humidity alarm
setpoints are disabled at the unit controls, then the MR1 will
display 00 for the setpoint. The MR1 is not able to remotely
enable alarm setpoints.
The MR1 will annunciate any alarm transmitted by the
Environmental controls. Table 4 catalogs the available alarms
by microprocessor level.
