PULSE EVALUATION SYSTEM
If the unit is supplied with AC voltage, the low voltage supply for the pulse
pick-up meets the SELV criteria.
The device shall be supplied from an isolating source and protected by an over-
current protection device such that the limited voltage circuit requirements in
accordance with UL 508 are met.
Connection of pulse pick-ups
D 100 provides approx. 24V DC (max. 30 mA) for the supply of pulse pick-ups.
Pulse pick-ups which need higher voltage/higher current consumption must
have an external supply. In this case the reference point of the external volta-
ge must be connected to terminal 6; the positive pole of the external power
supply must not be connected with the D 100.
Please also adhere to the SELV criteria for the pulse pick-up connection so that
there is no dangerous contact voltage at the sensor which can enter the unit!
