Connection Of Reset Button To Adam Ossd-Reset - ABB Eden OSSD Product Manual

Connection of Reset button to Adam OSSD-Reset

Adam OSSD-Reset is a model prepared for monitored local reset. A reset light button can be
connected to pin 5 and Adam OSSD handles the monitored reset and the indication lamp of the
Reset button. Each Eden with a local reset can be reset individually and independently of the
others. Only when all Eden units in the safety circuit have been reset, the safety circuit itself is
reset and the machine can be restarted.
Any button with a NO-contact and an indication lamp can be used. See electrical connection below.
The maximum current consumption for the indication lamp is 30 mA. Smile 12RF and Smile 12RG
are Reset buttons with indication lamps from ABB indented to be used together with Adam OSSD-
Reset. The minimum current consumption needed through the lamp is 10 mA. If no lamp is used, a
4.7 kOhm resistor can be used instead.
The reset signal is accepted as valid only when the reset signal is high for more than 100 ms but
less than 3 s.
Cable length between Reset button and Adam sensor: max 10 m.
