“WARNING – SETPOINT OVERRIDE”
A blank BRAM battery-backed memory device (IC lo-
cation U52 on Microboard) or a failure of this device
was detected during the initialization process that oc-
curs when power is applied to the Control Center. Due
to this failure, any or all of the programmed Setpoints
could have been corrupted. Therefore, all Setpoints
have been automatically changed to their Default
values. All Setpoints will have to be programmed to
their desired values. This message will clear when the
WARNING RESET key is pressed in OPERATOR (or
higher) access level.
“WARNING – CONDENSER – HIGH PRESSURE
LIMIT”
The Condenser Pressure exceeds the High Pressure
Warning Setpoint threshold, programmed by a Service
technician logged in at SERVICE access level. While
this condition is in effect, the Pre-rotation Vanes are in-
hibited from further opening. This message automati-
cally clears and the Vanes are permitted to open when
the Condenser pressure decreases to 5 PSIG below the
Setpoint.
“WARNING – EVAPORATOR – LOW PRES-
SURE LIMIT”
The Evaporator pressure has decreased to the Warning
threshold. This threshold is fixed in Water cooling ap-
plications. In Brine cooling applications, the threshold
is a fixed amount above the programmable safety shut-
down threshold. The Safety threshold in Brine applica-
tions is determined by the Brine solution and is deter-
mined by the YORK Factory. While this condition is
in effect, the Pre-rotation Vanes are inhibited from fur-
ther opening. This message automatically clears and
the Vanes are permitted to open when the Evaporator
pressure increases to the reset value.

“WARNING – MOTOR BEARING LUBE SUG-
GESTED”
(Software version C.MLM.11.02.xxx (and later) or
C.OPT.11.02.300 (and later)).
The Operating Hours Since Last Motor Lubrication
has exceeded 1000 hours (the greater of either Motor
#1 Operating Hours or Motor #2 Operating Hours is
used for this calculation). This warning will be dis-
played until manually cleared by the Operator or the
Operating Hours Since Last Motor Lubrication exceed
1200 hours, whereupon it is replaced by the message
“Warning – Motor Bearing Lube Required” below.
The Operator clears this message by entering his/her
initials, name or user ID in Operator Access Level (or
higher) using the Motor Lube Acknowledge key on the
Motor Lubrication Screen. Refer to the Motor Lubri-
cation Screen for entry instructions. This entry implies
both motors were lubricated. The date and time of this
entry is automatically logged as the “Date of Last Mo-
tor Lubrication” and “Time of Last Motor Lubrica-
tion”. It also resets the “Operating Hours Since Last
Lubrication” to zero. The date this warning occurs is
stored as the “Date of Last Motor Lubrication Warning
or Fault”. With software version C.OPT.11.03.01.004
(and later), this warning message will only be dis-
played if the AUTO LUBE setpoint on the Motor Lu-
brication Screen enabled.
“WARNING – MOTOR BEARING LUBE RE-
QUIRED”
(Software version C.MLM.11.02.xxx (and later) or
C.OPT.11.02.300 (and later)).
The Operating Hours Since Last Motor Lubrication has
exceeded 1200 hours (the greater of either Motor #1
Operating Hours or Motor #2 Operating Hours is used
for this calculation). This warning replaces “Warning
– Motor Bearing Lube Suggested” above. This warn-
ing is displayed until manually cleared by the Opera-
tor or the Operating Hours Since Last Motor Lubrica-
tion exceed 1400 hours, whereupon it is replaced by
the message “Motor – Lack of Bearing Lubrication”
below. The Operator clears this message by entering
his/her initials, name or user ID in Operator Access
Level (or higher) using the Motor Lube Acknowl-
edge key on the Motor Lubrication Screen. Refer to
the Motor Lubrication Screen for entry instructions.
This entry implies both motors were lubricated. The
date and time of this entry is automatically logged as
the “Date of Last Motor Lubrication” and “Time of
