After power-up, the
display shows date,
Current time and value
of sensor 1.
Operating
By pushing the 'up/down' keys you
can select the desired values.
Every keypress brings you to the
next recorded value. Holding an
'up' or 'down' key effects an
automatic, accelerating scrolling.

Holding the button 'P' for more than 1 sec. brings you to the parameter page. Select parameter
by the 'up/down' keys (see parameter descriptions on the next pages). Holding the 'P' button
again brings you back to the sensor 1 page.
Every push on button 'P' brings you to the
page of the next sensor.
z
Select desired parameter by the 'up/down' keys
z
Press 'P'-key short
z
An access code is
requested
z
Enter access code by
'up/down' keys
The code is related from the time of the day as the sum of the hour (0 to 23) plus ‘10’.
Example
:
At 9:35 a.m. the code is 9 + 10 = 19.
At 9:35 p.m. the code would be 21 + 10 = 31
z
Notation of parameter flashes
z
Change value by the 'up/down' keys
z
Press 'P'-key short
z
Select new parameter if necessary
If you have pressed the 'P' key longer than 1 second or no key is pressed for about 1 minute
after entering the code, the display will switch back to the actual value of sensor 1.
Programming / Access Authorization
Organisation of the display pages
All parameters and values are partitioned on four
sensor pages and a parameter page. The sensor
pages contain the recorded values. The parameter
page contains setpoints, times, error messages,
etc. Operating the MiniMEP is very easy by three
keys. Key 'P' changes the pages, with the up/down
buttons you are able to scroll the lists or to change
values.

Reset of Error Messages
If an error message occurs,
push
shortly
Buzzer and relay will be reset, but will come
back after the set alarm repetition time. If an
error with a higher priority occurs, it will come
at once.
Buzzer / Relay Test
To test, if the internal buzzer and the alarm
relay works correctly,
push
and
at the same time while the actual values are
displayed. The buzzer sounds and the relay
switches off as long as you press the keys.
P
Error codes
If a failure occurs, the MiniMEP generates an
error message by de-activating the alarm relay
and switching ON the internal buzzer.
Additionally, the display starts flashing to get
your attention. Each error message has a
priority level. If several messages occur, the
messages with higher priority are displayed on
top, messages with lower priority are blinded
by the higher ones.
x34-types only
: If the current inputs
get > 20mA or if they are not connected:
display shows 100%, no error
message.
'——' ................... no error
'Poff' .................... main power was switched off

Reading the Current Error
While the display flashes, you can read the
current error by holding
for > 1 sec.
Then parameter (
actual error
) will be displayed
