2 The equipment of Memmert cabinets Series UE, BE, SE. ULE, SLE consists of:
electronic PID controllers with programmable start-up delay and hold time, set
temperature dependent operation and repeat function. The controller incorporates
permanent power matching and a time-saving self-diagnostic system for rapid fault
finding (see checklist)
a built-in timer for digital programme time selection up to 999 hours
RS232 interface according to DIN 12900-T1 for computer controlled and recorded
thermostating programmes with the MEMMERT software „CELSIUS for WINDOWS®“
(installation diskette and handbook)
The fan can be operated in two ways:
the fan can be switched on and off on the cabinet (in offline operation) or by the
programme
with PC control via the interface using the MEMMERT „CELSIUS for WINDOWS®“ (online
operation) the fan speed can in addition be adjusted by the programme in 10% steps.
Technical data summary
A Pt 100 DIN A in 4-wire circuit measures the temperature in the working chamber.
The temperature-set-accuracy is 0,1ºC for BE types and 1ºC UE/SE and ULE/SLE types.
Ovens Series UE/SE/BE have natural air circulation.
Series ULE/SLE ovens have circulation assisted by a fan.
Ambient
conditions
Ambient temperature 5ºC - 40°C, rh max. 80%. Overvoltage Category II.
Contamination degree: 2 according to IEC 664
Setting tem-
perature range
20ºC to nominal temperature (See rating plate).
Min. working
temperature
range
A stable temperature control of ovens without fan resp. with fan
switched-off can be guaranteed from 5°C above ambient temperature.
When the fan of the models ULE / SLE is switched on, the working
temperature can be set from 10°C degrees above ambient up to the
nominal temperature = maximum temperature (according to rating
plate).
Max. working
temperature range
Nominal temperature = maximum temperature (see rating plate).
Overheat
safety device
Serial adjustable overheat control in compliance with DIN 12880 Class
3.1; Class 2 protection (adjustable temperature limiter) available on
request.
