Single channel protection door monitoring.
Using the single channel protection door
monitoring terminals X3 and 53, 54 and 42, 41
and T11, X1 and X2, T22 and T12 must be
bridged. In this application these contacts are
not available any more. If the protection door
monitoring switch S1 is closed the output
contacts remain unchanged. The device will be
activated by pressing the release switch.
Contacts 13-14, 23-24 and 33-34 close with a
delay of approximately 100 ms. When opening
the protection door switch the contacts return to
their normal position without delay.
With this application the requirement of
redundancy in the protection door switch is not
accomplished.
Dual channel protection door monitoring.
With the dual channel protection door monitoring
terminals T22 and T12 are not bridged. The
function is similar to application No. 7. In this
application a fault in the protection door
monitoring switch will be detected.
Dual channel protection door monitoring with
extended control of the release switch.
If the protection door switch is closed, the output
contacts remain unchanged. Through a short
operation of the protection door switch contacts
13-14, 23-24 and 33-34 close after the reopening
of the switch with a delay of approximately 100
ms. After opening the protection door switches
the contacts return to their normal position without
delay.
Dual channel protection door monitoring time
with automatic activation and inf inite delay
between channels.
In this application the activation of the device
works automatically, since terminals T11 and T34
are bridged. If the protection door switch is
closed, the contacts close with a delay of
approximately 100 ms. After the opening of the
protection door switch the contacts return to their
normal position without delay (this application can
only be used in a restricted temperature range of
+40
°C).
