Monitoring continues while EntryRAE is in Diagnostic Mode.
Diagnostic mode allows users to set the pump stall setpoint. This should
only be done if your EntryRAE is going into a pump alarm when the
pump is not blocked, or if the EntryRAE does not go into pump alarm
when you block the pump inlet by holding your fi nger over it.
Entering Diagnostic Mode

diagnostic screen blanks. Then release the keys
and the values reappear.
2. Press @ 7 times to cycle through the diagnostic
screens until you reach the pump diagnostic
screen. The fi rst, CO, H

time screens are used for factory operation and
testing only. The pump diagnostic screen displays
a high and low pump rate. The fi rst digit of the last
number blinks.
3. To set the pump stall alarm, write down the “Hi”
value as found, and then block the pump inlet
while the pump is running (about 5 seconds), until
the “Hi” reading stabilizes.
4. Write down the new “Hi” value. Add the two “Hi”
values together, and then divide by two to get the
average value.
5. Enter the average into the bottom number on the
screen using the Y and N keys to increase and
decrease the digits, and @ to move between
digits.
6. Once the average is entered, press @ until you
see the blinking “?”. Press Y to save the pump
stall threshold value.
7. Exit the diagnostic mode by pressing @ and Y
together until the screen changes. Gas readings
may take a second to appear.
