Status Menu: The status menu displays the current coolant
temperature in °C or will display an alarm type should an alarm
occur.
Pressing the UP or DOWN keys with # of cycles set to zero will
change the set point temperature upon pressing the START key.
Parameter Input Menu: The parameter input menu allows input of
operating temperatures, soak times, number of cycles desired,
temperature units desired, time units desired, the alarm temperature
range and an offset temperature to change the displayed temperature.
SETTEMP1 = Set point of first control temperature.
If # OF CYCLES is set to zero, this is the control temperature.
SETTIME1 = Soak time at temperature 1.
Not used if # OF CYCLES is set to zero.
SETTEMP2= Set point of second control temperature.
Not used if # OF CYCLES is set to zero.
SETTIME2 = Soak time at temperature 2.
Not used if # OF CYCLES is set to zero.
# OF CYC = Number of cycles between temperature1 and
temperature2. If set to zero, the chiller will control at
temperature SETTEMP1.
ALRM TMP = +/- Alarm temperature set point.
If the current temperature is outside of the set point +/- the dry
contact alarm will open.
OFFSET = Used to adjust the current temperature displayed.
Entering 5 ºC will increase the displayed temperature by 5 ºC.
Typically used to match temperatures with an external sensor.
Also adjusts RS-232 temperature reported.
CHG PWD = Y/N Entering Y allows user to change the password
allowing entry into the parameter input menu.

The Denali M1 has one normally closed dry contact alarm for
temperature out of range or system failure, located on pins 1 & 6 of
the 9-pin dsub connector.
A list of system failures causing the dry contact alarm to open can be
found in Section 6. In the event of a failure, the alarm type will be
shown on the front display.
