A schedule sheet (page 21) is provided so the user
can predetermine the weeks program. It is strongly
recommended to use this schedule sheet before
any programming is started.
12) SET KEY - This key has two functions. The
first being to select the continuous or program
mode of operation. The second being to select a
setpoint temperature if the continuous mode of
operation has been selected.
13) UP/DOWN ARROW KEYS - These keys are
used to increase or decrease a desired value.
14) REPEAT KEY - This key is a time saver key.
When in the program mode, pressing this key will
duplicate the program setting from the current day
to the other 6 days.
15) CAL KEY - This key is used to calibrate the
incubator to a certified/traceable thermometer.
16) MUTE KEY - This key is used to silence the
internal audible alarm and to also deactivate the
external alarm device if one is being used.
17) LIGHT KEY - This key, in the continuous mode,
will turn the internal light on or off. In the program
mode, this key is disabled. The internal light will
not be allowed to operate at a setpoint temperature
below 10 degrees in either the CONTINUOUS or
PROGRAM mode.
18) LOCK KEY - This key is used to enable or
disable the keyboard.
19) CLOCK KEY - This key is used to select the
day, hours, and minutes.
-Explanation of Auxiliary Panel-
On the left side of the incubator control panel there
is an auxiliary panel which has the items shown in
the figure on the next page. They are described
as follows:
1) FUSE - This fuse is in line with the main power
cord that comes into the incubator. The rating of
this fuse is printed above the fuse holder. The
physical size of this fuse is 5 MM x 20 MM.
2) ALARM RELAY - This Alarm Relay output is
provided to the user for the purpose of remotely
monitoring the incubator in case of a high or low
temperature alarm condition. This alarm relay will
operate just as the audible alarm would. The
contact itself is an isolated form C (normally open/
normally closed) dry contact. This contact is to be
used for low voltage class 2 connections only. The
contact rating is 24 volts, 1.25 amps resistive.
Typical usages of the output are shown below.
In this configuration, the light will illuminate
whenever the unit goes into an alarm condition,
High or Low.
In this configuration, the light will go off in a high or
low temperature alarm condition.
NOTE
WIRING MUST CONFORM TO ALL LOCAL
ELECTRICAL CODES.
3) RS-232 OUTPUT (Optional Kit P/N 3166245) -
This output is used for two way communications
between the incubator and a personal computer.
With the use of a communications/modem software
program, the user can record the temperature of
the incubator at their selected time periods and
store it in a file for use with a spreadsheet program.
The user can also change the setpoint temperature
from their personal computer and periodically
monitor the actual temperature, setpoint
temperature, and alarm status.
