Open the CO

supply's pressure reducer valve and set a CO

primary pressure of 2.0 bar / 29 psi.

Set the main power switch (2) to position I. The pilot lamp shows the unit is ready for operation. There is a

subsequent brief startup phase in which the display items at the edges of the upper controller display light

up successively.

After a few seconds, the upper display shows the current interior temperature of the C 150 and the lower

display shows the current CO

interior concentration. The lit LEDs at the right of the display show that the

temperature is displayed in °C and the CO

concentration is displayed in vol.-% CO

Figure 19: Normal display of controller after turning on the

incubator, showing the current temperature and CO

val-

ues (example)

Set the controller to the desired temperature and CO

set points that are to be used to operate the C 150.

The yellow LED indicates that the heating is active, and the yellow LED indicates that the CO

valve is open.

Only insert samples into the C 150 when it has reached its stable operating state:

Temperature: Equilibration time is approx. 2 hours.

: After approx. 5 minutes, the CO

concentration equilibrates automatically to the preset value.

If there is no accordance between the actual and set value shown in the display, proper opera-

tion of the unit is not guaranteed.

Instructions when observing leakage of condensate from the CO

sensor system and CO

fluctua-

tion:

In the case of CO

fluctuations and concomitant condensate leakage from the injection and suction noz-

zle of the CO

sensor compartment after start-up or when taking the unit back into service, the unit should

be left to dry open for at least an hour running at 37 °C with the water pan empty. This will result in flush-

ing the sensor compartment and tubing from humid air. Removing the condensate from the CO

sensor

system will ensure a turbulence-free CO

measurement.

7. Controller RP1 operating modes

The controller provides three operating modes HAND (chap. 7.2), USER (chap. 7.3), and LOCK (chap.

7.4). In operating modes HAND and USER, you can call up several operating functions and set / modify

their values.

Operating mode USER is password protected. On delivery, the password is set to “1” (factory setting).

You can change the password in operating function “PA.U” (chap. 7.3).

You can also implement password protection for operating mode HAND (chap. 7.4).
