Programming the Ethernet Controller
Ice Qube offers an optional Ethernet controller. The Ethernet Thermal Management Center (ETMC) is an innovative
approach to monitoring and controlling the thermal equipment on electrical, electronic, and telecommunications
equipment. With the ETMC, it is easy to connect the thermal management equipment to a network anywhere there is
access to a node. Ice Qube ETMC has all the features of the standard digital controller, plus a user-friendly LCD
message center, expanded temperature and alarm ranges, improved functionality, and the capability to communicate
on an Ethernet network. For more information or questions concerning the ETMC contact Ice Qube technical
assistance.
Alarm Operation
1. The enclosure temperature is above or below the alarm set-point:
The “Alarm” LED will light, the display will flash, the “HI” or the “LO” LED will flash, and the audible
alarm sounds (if activated.) The enclosure temperature must rise or fall 2°F (1°C) before the alarm will
reset.
2. The condenser temperature is above the condenser alarm set-point:
The “Alarm” LED lights, the display flashes the condenser temperature, and the audible alarm sounds (if
activated.) the condenser temperature must fall 4°F (2°C) before the alarm will reset. The above alarms
can be manually reset by entering the PIN code into the system.
3. The filter day timer has expired:
The “Alarm” LED lights, the display flashes “FIL”, the “Filter” LED flashes with the display and the
audible alarm sounds (if activated.) The filter alarm may be cleared by pressing “4 Exit”.
4. The power is turned off:
The “Alarm” LED lights, and the display flashes “OFF” indicating someone has manually interrupted
power to the motors’ electrical circuits. This alarm will be rest when the Por “ON” has been selected in the
program menu. (Version 3.18 and later only)
5. Optional Alarm Output:
Ice Qube offers an optional dry contact alarm output (XO3) that provides both a normally open (close on
alarm) and a normally closed (open on alarm) set of contacts. This alarm signal is provided from a relay
through a 3 conductor cable (Black/Common, White/Normally Open, and Red/Normally Closed) passing through a
strain relief to the left of the internal controller.
6. Sensor Malfunctions:
E-O: Evaporator sensor open
E-C: Evaporator sensor shorted
C-O: Condenser sensor open
C-C: Condenser sensor shorted
Alternating E-O and C-O: Sensor connector disconnected
7. Incorrect Voltage Supply:
A continual flashing value of the program version (“3.1x” where x indicates current program version) on
the display screen indicates the supply voltage is either too high or too low.
