Figure 5-13 Example with external (left) and internal (right) relay
Category 2: outputs with category 2 single relays with OTE outputs. Each PSR-M-EF6
module can have up to four outputs of this type.
Output “O
TE” (Output Test Equipment) is logic “1” when no internal or external error is pres-
ent.
Properties:
– Internal relays are always monitored.
– Monitored EDM feedback.
– Each output can be set: automatic, manual or manually monitored reset.
– “External K time monitoring” cannot be activated for a manual reset. On activation of the
“External K time monitoring” option, the “automatic” reset type (and therefore EDM
feedback) is activated automatically.
– If you would like to use manual restart, there is a special logic for this. See note below
regarding “OTE”.
