SECONDARY MESSAGE
OCCUPIED MODE Chiller is starting. Time schedule is occupied (OCCUPIED? = YES).
REMOTE CONTACT Chiller is starting. REMOTE CONTACTS OPTION is set to ENABLE.
CLOSED Remote contacts input on terminal block TB1 terminals 23 and 24 are closed.
START COMMAND Chiller is starting. CHILLER START/STOP in MAINSTAT manually forced to START.
IN EFFECT
OCCUPIED MODE Chiller is starting after power failure. Time schedule is occupied
(OCCUPIED? = YES).
REMOTE CONTACT Chiller is starting after power failure. REMOTE CONTACTS OPTION is set to
CLOSED ENABLE. Remote contacts input on terminal block TB1 terminals 23 and 24
are closed.
START COMMAND Chiller is starting after power failure. CHILLER START/STOP on MAINSTAT
IN EFFECT manually forced to START.
SECONDARY MESSAGE
BY 4-20 mA SIGNAL Auto chilled liquid reset active based on external input. ENABLE RESET
TYPE =1. A non-zero temperature reset based on a 4-20 mA signal on
CCM J5-3 and J5-4 is being added to the SETPOINT to determine the
CONTROL POINT. See TEMP_CTL screen.
REMOTE TEMP SENSOR Auto chilled liquid reset active based on external input. ENABLE RESET TYPE =2.
A non-zero temperature reset based on the remote sensor signal on CCM J4-13
and J4-14 is being added to the SETPOINT to determine the CONTROL POINT.
See TEMP_CTL screen.
CHL TEMP DIFFERENCE Auto chilled liquid reset active based on cooler Delta T. ENABLE RESET TYPE =3.
A non-zero temperature reset based on the difference between the ENTERING
CHILLED LIQUID and LEAVING CHILLED LIQUID is being added to the
SETPOINT to determine the CONTROL POINT. See TEMP_CTL screen.
LEAVING CHILLED LIQUID Default method of temperature control. ECL CONTROL OPTION = DSABLE.
Chiller capacity is being controlled so the LEAVING CHILLED LIQUID temperature
is being maintained within 1/2 of the CHILLED LIQUID DEADBAND on either side
of the CONTROL POINT. See TEMP_CTL screen.
ENTERING CHILLED LIQUID Entering Chilled Liquid (ECL) control enabled. ECL CONTROL OPTION
= ENABLE. Chiller capacity is being controlled so the ENTERING CHILLED
LIQUID temperature is being maintained within 1/2 of the CHILLED LIQUID
DEADBAND on either side of the CONTROL POINT. See TEMP_CTL screen.
TEMPERATURE RAMP Ramp Loading based on LEAVING CHILLED LIQUID or ENTERING CHILLED
LOADING LIQUID is in effect. PULLDOWN RAMP TYPE = 0. Capacity inhibit is in effect
because LEAVING CHILLED LIQUID or ENTERING CHILLED LIQUID has fallen
below the ramping temperature pulldown setpoint. See RAMP_DEM screen.
BY DEMAND RAMP Ramp Loading based on PERCENT LINE CURRENT or PERCENT LINE
LOADING KILOWATTS is in effect. PULLDOWN RAMP TYPE = 0. Capacity inhibit is in
effect because PERCENT LINE CURRENT or PERCENT LINE KILOWATTS has
exceeded the ramping active demand limit. See RAMP_DEM screen.
BY LOCAL DEMAND Actual demand has exceeded ACTIVE DEMAND LIMIT. 20mA DEMAND LIMIT
SETPOINT OPTION is DISABLED. ACTIVE DEMAND LIMIT is set equal to BASED DEMAND
LIMIT. PERCENT LINE CURRENT or PERCENT LINE KILOWATTS is greater than
ACTIVE DEMAND LIMIT.
BY 4-20 mA SIGNAL Actual demand has exceeded ACTIVE DEMAND LIMIT. 20mA DEMAND
LIMIT OPTION is ENABLED. ACTIVE DEMAND LIMIT is adjusted based on
4-20 mA signal received on CCM J5-1 and J5-2. PERCENT LINE CURRENT or
PERCENT LINE KILOWATTS is greater than ACTIVE DEMAND LIMIT.
BY CCN SIGNAL Actual demand has exceeded ACTIVE DEMAND LIMIT. Chiller CONTROL
MODE = CCN. Value of ACTIVE DEMAND LIMIT is being forced by a CCN
device. PERCENT LINE CURRENT or PERCENT LINE KILOWATTS is greater
than ACTIVE DEMAND LIMIT.
BY LOADSHED/REDLINE Actual demand has exceeded ACTIVE DEMAND LIMIT. Chiller CONTROL
MODE = CCN. Value of ACTIVE DEMAND LIMIT was set equal to PERCENT
LINE CURRENT or PERCENT LINE KILOWATTS at the time a Redline command
was received by the loadshed POC (Program Outboard Control). PERCENT LINE
CURRENT or PERCENT LINE KILOWATTS is greater than ACTIVE DEMAND LIMIT.
See LOADSHED screen.
HOT GAS BYPASS HOT GAS BYPASS OPTION is set to ENABLE and HOT GAS BYPASS RELAY is ON.
BY LOCAL SIGNAL ACTIVE DEMAND LIMIT has been manually forced on MAINSTAT screen.
ICE BUILD MODE ICE BUILD OPTION is set to ENABLE and chiller is running under Ice Build
temperature control.
MOTOR LOAD CURRENT Actual demand has exceeded ACTIVE DEMAND LIMIT. Capacity inhibit is active
because PERCENT LOAD CURRENT is greater than 100%.
VFD LINE CURRENT Actual demand has exceeded ACTIVE DEMAND LIMIT. Capacity inhibit is active
because PERCENT LINE CURRENT exceeds 100%.
