Application Example of Timed Annunciator Set
When the special auxiliary relay M9049= “ON” and any assigned annunciator of S900 ~ S999 is activated, then
M9048= “ON” and D9049 will display an activated annunciator number. If there is more than one annunciator
being activated simultaneously, D9049 will display the smallest active annunciator ID number.
The following chart is an ANS (Timed Annunciator Set) / ANR (Annunciator Reset) application
X20: Forward Switch
Y20: Forward Device
S900: Forward Annunciator
X21: Backward Switch
Y21: Backward Device
S901: Backward Annunciator
X22: Front End Position Switch
Y27: Alarm Indicator
X23: Back End Position Switch
X27: Annunciator Reset Button
When the forward switch contact X20= “ON”, the forward device Y20= “ON”
and remain. Y20 will become “OFF” when the object reaches the front end
position (X22= “ON”).
When the backward switch contact X21= “ON”, the backward device
Y21= “ON” and remain. Y21 will become “OFF” when the object reaches
the back end position (X23= “ON”).
When M9049= “ON”, the alarm monitor will be activated,
where M9048 and D9049 are effective.
If Y20= “ON” for more than 6 seconds and does not reach the
front end position, then S900= “ON”.
If Y21= “ON” for more than 6 seconds and does not reach the
back end position, then S901= “ON”.
The alarm indicator Y27= “ON” if any one of annunciator is “ON”.
After the problem is cleared, press X27 once to reset the annunciator.
