Binder CB 160 - Setpoint Entry; Note When Setting High Gas Concentrations

CB (E6.1) 07/2017 Page 48/145
7. Setpoint entry
7.1 Setting ranges
Temperature
7 °C / 12.6 °F above ambient up to 60 °C / 140 °F
CO
2
0 vol.-% up to 20 vol.- %
O
2
(chamber with O
2
control) 0.2 vol.-% up to 95 vol.-%
When changing the temperature setpoint, check the setting of the overtemperature safety
controller class 3.1 (chap. 14.2).
With setpoint type “Limit”, adapt the safety controller always when changing the temperature
setpoint.
When setting a lower temperature setpoint, in order to save time, we recommend cooling
down the chamber by turning it off and opening both chamber doors.
When setting a lower CO
2
setpoint, the CO
2
gas must be able to escape first. Open both
chamber doors for this purpose.
7.2 Note when setting high gas concentrations
Notes on handling carbon dioxide (CO
2
)
Carbon dioxide (CO
2
) in high concentrations is hazardous to health. It is colorless and almost odorless
and therefore practically imperceptible. Vent out any CO
2
gas that may escape via good room ventilation
or a suitable connection to an exhaust system. We recommend installing a CO
2
warning system.
WARNING
High concentration of CO
2
(> 4 Vol.-%).
Danger of death by suffocation.
Danger of poisoning.
∅ Do NOT set up chambers in non-ventilated recesses.
 Ensure technical ventilation measures.
 Observe the relevant regulations for handling CO
2
.
If CO
2
is released, leave the area und inform the security service or fire department.
Chamber with O
2
control: Notes on handling oxygen (O
2
)
Oxygen (O
2
) is colorless and almost odorless and therefore practically imperceptible. It promotes burns,
which can proceed explosively. There is a fire hazard for flammable oxygenated materials, e.g. clothes
and hair. O
2
is heavier than air and may accumulate in low-lying areas.
