Operating instructions

6 UP/BP/ULP/SLP 400 - 800
Technical data summary
A Pt 100 DIN A in 4-wire circuit measures the temperature in the working chamber.
The temperature setting accuracy is 0.1ºC for BP types and 1ºC on UP/SLP types.
Ovens Series UP, BP, have natural air circulation.
Series ULP and SLP 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 tempera-
ture range
20ºC - to nominal temperature (see rating plate).
Working tem-
perature range
From 5 ºC above ambient to nominal temperature = maximum
temperature (see rating plate).
When the fan of the models ULP / SLP 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).
Overheat safety
device
Standard adjustable overheat control in compliance with DIN 12880
Class 3.1 and additional mechanical temperature limiting device Class 1.
Class 2 protection (adjustable temperature limiter) available on request.
Class Aim of
protection
Scope of protection Safety device Safety measures
1
Protection of
the oven
No risk liable to ori-
ginate from the oven in
the event of a fault
TB
(temperature limiting device)
automatically shuts off the oven if the
user-selected temperature limit is
exceeded.
2
No risk originating
either from the oven or
its contents in the event
of a fault
TWB
(adjustable temperature limiter)
automatically shuts off the oven if the
user-selected temperature limit is
exceeded.
3.1
Protection of
the oven, the
environment
and the
contents of
the oven
The contents of the
oven are protected
against overheating
TWW
(adjustable overheat controller)
takes over control of oven if temperature
is exceeded.
Special safety
measures
required
depending on the
purpose for
which the oven is
used
2.1 Electrical supply
50 or 60 Hz. Insulated supply incorporating earth conductor according to EN 61010,
Protection IP 20, no humidity protection according to DIN 40 050. Interference
suppression Grade N according to VDE 0875, limiting values to Class B, Group 1.
A
fuse 250V/15A fast is used for unit protection (3 fuses on units for 400 V 3ph/N powe
r
supply).
When connecting a Memmert oven to the supply you have to observe any local
regulations which apply.
(e.g. in Germany, DIN VDE 0100 with FI - safety device).
