Application Examples
shows the Input Configuration tab of the ArmorBlock Module
Properties. In this example, Points 0 and 1 monitor the OSSD outputs of the
safety switch. The Type must be set to Equivalent, and Mode must be set to
Safety. Points 4 and 5 monitor the status of the output contactors K1 and K2.
The Type should be set to Equivalent. The discrepancy time will be dependent
on the contactor device — a value other than 30 may be needed. Safety pulse
testing is used to detect potential faults in the monitoring circuit.
Figure 26 - Module Properties — Input Configuration
shows the Test Output tab of the ArmorBlock Module Properties.
In this example, Points 0 and 1 are set to Standard. This allows these points to
be controlled by the program. Point 0 applies power to the 440G-LZ. By
setting it to standard, the user can programmatically turn this point off and on
if the 440G-LZ switch has a fault condition. Point 1 is the lock/unlock
command. In this example, the 440G-LZ is a PTR type, so 24V unlocks the
switch. Points 4 and 5 are used to monitor the contactor outputs and are set to
Pulse Test.
Figure 27 - Module Properties – Test Output
shows the Output Configuration tab of the ArmorBlock Module
Properties. Points 0 and 1 drive the output contactors K1 and K2. The point
Types are set to Dual, and the Modes are set to Safety.
