Description of the function
The hours counter monitors input En. As long as the status at this input is 1, x-Messenger calculates the time
expired and the time-to-go MN. x-Messenger displays these times when set to configuration mode. The
output is set to 1 when the time-to-go is equal to zero.
You reset output Q and the time-to-go counter to the specified value MI with a signal at input R. The operation
hour counter OT remains unaffected.
You reset output Q and the time-to-go counter to the specified value MI with a signal at input Ral. The
operation hour counter OT is reset to 0.
Depending on your configuration of the Q parameter, the output is either reset with a reset signal at input R
or Ral, or when the reset signal is 1 or the En signal is 0.
Limit value of OT
The values of the operating hours in OT are retained when you reset the hours counter with a signal at input
R. The hours counter OT continues the count as long as En = 1, irrespective of the status at the reset input
R. The counter limit of OT is 99999 h. The hours counter stops when it reaches this value.
In programming mode, you can set the initial value of OT. The counter starts operation at any value other
than zero. MN is automatically calculated at the START, based on the MI and OT values.
Example: MI = 100, OT = 130, the result is MN = 70
Parameter preset
In eSmsConfig, you can define MI and an OT start value.
You determine that Q does not depend on En by selecting the corresponding check box.
Retentivity with the hours counter
The hours counter in the x-Messenger is generally retentive.
However, if the values of the hours counter are lost after a power failure, then select the respective block in
