2. Chamber description
BINDER drying and heating ovens FED are equipped with an electronic PID-controller with digital display.
The temperature is indicated with an accuracy of one degree.
The chambers are heated electrically and are ventilated by fan-assisted, forced-air circulation. They FED
are equipped with a temperature safety device according to DIN12880 (chap. 7).
The APT.line™ preheating chamber system guarantees high level of spatial and time-based temperature
precision, thanks to the direct and distributed air circulation into the interior. The fan supports exact
attainment and maintenance of the desired temperature accuracy.
The chambers are regularly equipped with a temperature safety device according to DIN12880:2007
(chap. 7).
The inner chamber, the pre-heating chamber and the inside of the doors are all made of stainless steel
V2A (German material no. 1.4301, US equivalent AISI 304). When operating the chamber at
temperatures above 150 °C, 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 equipped with a serial interface RS 422 for computer communication, e.g. via the
communication software APT-COM™ 3 DataControlSystem (option, chap. 8.1). For further options, see
chap. 12.5.
The model FED 720 is equipped with four castors. Both front castors can be locked by brakes.
The chamber can be operated in a temperature range of 5 °C / 9 °F above room temperature up to 300
°C / 572 °F.

•The domestic socket must also provide a protective conductor. Make sure that the connection of the
protective conductor of the domestic installations to the chamber’s protective conductor meets the
latest technology. The protective conductors of the socket and plug must be compatible!
•Prior to connection and start-up, check the power supply voltage. Compare the values to the specified
data located on the chamber‘s type plate (chamber front behind the door, bottom left-hand, chap. 1.4).
•When connecting, please observe the regulations specified by the local electricity supply company
and as well as the VDE directives (for Germany). We recommend the use of a residual current circuit
breaker.
•Pollution degree (acc. to IEC 61010-1): 2
•Over-voltage category (acc. to IEC 61010-1): II
CAUTION
Danger of incorrect power supply voltage.
Damage to the equipment.
Check the power supply voltage before connection and start-up.
Compare the power supply voltage with the data indicated on the type plate.
See also electrical data (chap.12.4).
To completely separate the chamber from the power supply, you must disconnect the power
plug. Install the chamber in a way that the power plug is easily accessible and can be easily
pulled in case of danger.
4.2 Connection to a suction plant (optional)
When directly connecting a suction plant the spatial temperature exactitude, the heating-up and the
recovering times and the maximum temperature will be negatively influenced. So no suction plant should
be directly connected to the exhaust duct.
Active suction from the chamber must only be performed together with extraneous air.
Perforate the connecting piece to the suction device or place an exhaust funnel at some
distance to the exhaust duct.

FED (E2) 08/2018 page 16/57
CAUTION
The exhaust duct will become hot during operation.
Danger of burning.
∅Do NOT touch the exhaust duct during operation.
5. Start up
5.1 Turning on the chamber
Warming chambers may release odors in the first few days after commissioning. This is not a
quality defect. To reduce odors quickly we recommend heating up the chamber to its nominal
temperature for one day and in a well-ventilated location.
1. Insert the power plug into a suitable socket (chap. 4.1).
2. Turn on chambers at the main power switch (10)
The green “Standby“ LED illuminates.
3. Press until the display lights up.
The controller is now in normal display (actual value display).
If the chamber is operating (time functions “Continuous operation”, or
“Timer operation” with the set time just running down chap. 6.3
), the
actual temperature value (example: 22 °C) is displayed
If the chamber is in time function “Timer operation” with no time programmed or the set time run-off
(chap. 6.3), the chamber is inactive (no heating). The display alternately shows the actual temperature
value (example: 22 °C) and “tOff”:
Adjust the temperature safety device following any changes of the set-point (chap. 7).
5.2 Heating operation display
The heating is active as soon as the red heating control light in the
bottom right corner of the display slowly begins to flash depending on
the heat requirement (example: 70 °C):

FED (E2) 08/2018 page 17/57
5.3 Air change
Opening the air flap in the exhaust duct serves to adjust the
air change.
Without connecting a suction plant:
•If the air flap is open and the fan is operating, fresh air
comes in via aeration gaps.
•If the air flap is completely open, the spatial temperature
accuracy can be negatively influenced.
