Precautions to Be Taken When Connecting to Sensors or Signal
Output Sources
CAUTION
The maximum input voltage for direct input is indicated below. Applying a voltage exceeding
this value can damage the input section. To apply high voltage that is 42 V or higher, be
sure to connect through an isolated probe (700929 or 701947) or passive probe 702902.
Maximum input voltage: 42 V (DC + ACpeak) (CAT II)
The minimum input voltage is 0.2 Vpp. At voltage amplitude less than 0.2 Vpp, the
measured values may be unstable.
Attach/Remove the sensors after confirming that the rotating object to be measured is
stopped.
Set the preset to electromagnetic pickup (EM Pickup) only when using the electromagnetic
pickup.

ATTENTION
La tension d’entrée maximale de l’entrée directe est indiquée ci-dessous. Le fait d’appliquer
une tension dépassant cette valeur risque d’endommager la section d’entrée. Pour
appliquer une tension élevée de 42 V au moins, bien réaliser le branchement à l’aide d’une
sonde isolée (700929 ou 701947) ou d’une sonde passive 702902.
Tension d’entrée maximale : 42 V (c.c. + crête c.a.) (CAT II)
La tension d’entrée minimale est 0,2 Vpp. Pour une amplitude de tension inférieure à
0,2 Vpp, les valeurs mesurées risquent d’être instables.
Brancher/retirer les capteurs après avoir confirmé que l’objet rotatif à mesuré a été arrêté.
Prérégler le paramétrage sur détection électromagnétique (EM Pickup) uniquement lors de
l’utilisation de la détection électromagnétique.
Connecting the Electromagnetic Pickup
The DL850E/DL850EV allows power-generating electromagnetic pickup to be connected directly.
The DL850E/DL850EV does not support electromagnetic pickups that require external power
supply or those that require a terminator at the output.
To connect electromagnetic pickups, use BNC cables. Use cables that are appropriate for the
electromagnetic pickups being used.
When the input is set to electromagnetic pickup, determination is not made on whether the input
voltage level exceeds the specified input voltage range. Therefore, the LEDs (see page 3-10) do
not illuminate eve when the input voltage level is over range.
