7. POWER SUPPLY

Power can be supplied to the measuring instrument in any of the following

ways : Mains adapter 12 V / 1.0 A 

ZB 1212-NA7

Power supply cable, electr. Isol. (10 to 30 VDC, 0.25 A)  

ZB 3090-UK

Power supply cable, electr. Isol. (10 to 30 VDC, 1.25 A)  

ZB 3090-UK2

See product overview, Annex 14 and the following chapters.

7.1 Mains operation

To power these devices from the mains preferably use the mains adapter pro-

vided (for type see above); connect it to the socket DC (7). 

7.2 External DC voltage supply

The DC socket (7) can also be used to connect another DC voltage, 9 to 13 V
(minimum 200 mA).  For this connection use a cable with 2 banana plugs (ZB

5090-EK).   If, however, the power supply has to be electrically isolated from
the transducers or if a larger input voltage range (10 to 30 V) is required, then

an electrically isolated supply cable must be used (ZB 3090-UK).  It will then be
possible to use the measuring instrument in a 12-volt or 24-volt on-board sup-

ply system.

7.3 Sensor supply

An den Klemmen – und + im ALMEMO

®

-Stecker steht bei Netzbetrieb eine

Fühlerversorgungsspannung von 12V (400mA) zur Verfügung (selbstheilende

Sicherung 500 mA). Andere Spannungen (12V, 15V, 24V oder Referenzen für
Potentiometer   und   Dehnungsmessstreifen)   sind   mit   speziellen   Steckern   er-

reichbar (s. Hb. 4.2.5/6).

7.4 Switching ON / OFF, reinitialization

To switch the device ON / OFF press the ON / OFF key (2). 
To switch the device OFF press the ON / OFF key and hold down for approx. 1

second.   After the device is switched off the real-time clock continues to run
and all saved values and settings are retained intact.  
If interference (e.g. electrostatic or mains failure) causes the device to behave
abnormally, you are advised first of all to try clearing the problem by simply rei-

nitializing, i.e. switching off and then on again.
If this does not help then you are advised to restore all device programming to the

factory default settings. The device can be reset by setting the code switch G 

(1)

,

before switching on, to address 99. The device name, device programming with all

settings, memory and macros are deleted and the baud rate setting in the data ca-
ble is reset to 9600 baud. Only the time, device calibration and programming of the

sensors in the ALMEMO

®

 connectors remain unaffected.
