Trouble-shooting and Repairs
• Non-observance of warning messages in the Service Manual
• Trouble-shooting of live parts without specified safety measures
• Absence of a plausibility check to rule out erroneous inscription of electrical components
• Performance of repair work by untrained/insufficiently qualified personnel
• Inappropriate repairs which do not meet the quality standard specified by BINDER
• Use of replacement parts other than BINDER original replacement parts
• Electrical safety analysis not performed after repairs
2. Chamber description
BINDER incubators BD and BF and drying and heating ovens ED, FD and FED are equipped with an
electronic PID-controller with digital display.
The incubators BD and BF indicate the temperature with an accuracy of a tenth of a degree.
The drying and heating ovens ED, FD and FED indicate the temperature with an accuracy of
one degree.
All chambers are heated electrically. Incubators BD and drying and heating ovens ED are ventilated natu-
rally. Incubators BF and drying and heating ovens FD and FED are ventilated by fan-assisted, forced-air
circulation.
The concept of air conduction guarantees high level of spatial and time-based temperature precision,
thanks to the direct and distributed air circulation into the interior. With BF, FD and FED, the fan supports
exact attainment and maintenance of the desired temperature accuracy.
The chambers are regularly equipped with an overtemperature safety device class 1 acc. to DIN12880:2007
and with an overtemperature safety controller (overtemperature temperature safety device class 2 or class
3.1 acc. to DIN12880:2007), see chap. 7).
Material: The inner chamber and the inside of the doors are made of stainless steel V2A (German material
no. 1.4301, US equivalent AISI 304 and material no. 1.4016, US equivalent AISI 430). Drying and heating
ovens ED, FD and FED: When operating the chambers at temperatures above 150 °C / 302 °F, the impact
of the oxygen in the air may cause discoloration of the metallic surfaces (yellowish-brown or blue) by natural
oxidation processes. These colorations are harmless and will in no way impair the function or quality of the
chamber. The housing is RAL 7035 powder-coated. All corners and edges are also completely coated.
All chamber functions are easy and comfortable to use thanks to their clear arrangement. Major features
are easy cleaning of all chamber parts and avoidance of undesired contamination.
The chambers are regularly (FED) or optionally equipped with an Ethernet interface for computer commu-
nication, e.g. via the APT-COM™ 4 Multi Management Software (option, chap. 12.1) and with a USB inter-
face to read out the measured values in real time.
The models size 720 are equipped with
four castors. Both front castors can be locked by brakes.
Temperature ranges see technical data (chap. 16.4 - 16.8).
