RS-232C ALARM CODES
The following alarm codes may be transmitted in an AL or AH status message. Not all of
these codes are possible in every system:
1 CONDENSER HOT : The reading from the condenser RTD indicates a
temperature in excess of +50°C. The system microprocessor incrementally
reduces the evaporator valve drive to reduce the flow of refrigerant into the
evaporator. This effectively reduces the heat-rejecting capacity of the
system, which keeps the temperature in the condenser at acceptable levels.
2 LOW FREON: Indicates pressure of refrigerant is low. Have unit serviced by
Mydax or a qualified service center.
3 RTD OPEN : Indicates that one of the system RTD's has failed and the
system has shut down to protect itself. The main display shows which RTD is
faulty by giving its pin number location on the M1002 or M1005 circuit board.
4 PUSH RESET : The interlock loop has been broken and the reset switch must
be depressed to re-establish it.
5 FILL TANK #1 : The tank 1 low level sensor has tripped. If coolant is not
added "soon", the "empty" sensor trips and the system shuts down.
6 Inactive in this system.
7 FILL TANK #2 : The tank 2 low level sensor has tripped. If coolant is not
added "soon", the "empty" sensor trips and the system shuts down.
8 LOW FLOW : Indicates that a low flow condition exists in one of the
recirculating channels.
9 Inactive.
10 PHASE MISSING : Indicates one or two of the three electrical power phases
is missing. Inactive on single-phase units.
11 PHASE REVERSED : Indicates incorrect electrical power phase relationship.
May be corrected by reversing any 2 phases. Inactive on single-phase units.
12 Inactive in this system.
13 LOW AC LINE : Indicates a low voltage condition exists on the input AC line.
14 RESISTANCE LOW : Indicates that the deionized water resistivity has
dropped below the programmed limit.
15 TANKx TOO HOT / EXTREME TEMP : Indicates that the tank temperature is
either more than +10.0°C above its upper maximum set point, or too close to
freezing and that the system has shut down.
