Using Periodic Timers
The PM172E and PM172EH provide two programmable interval timers that
can be used for periodic recording and triggering operations on a time basis
through the Control Setpoints. When a pre-programmed timer interval
expires, the timer generates an internal event that can trigger any setpoint
(see “Using Alarm/Control Setpoints”).
To configure the device timers, select General Setup from the Meter Setup
menu, and then click on the Periodic Timers tab.
To run a periodic timer, specify a non-zero time period for the timer. The time
period can be set from 1 to 9999 seconds.
To stop a timer, set the time period to zero.
Using Control Setpoints
The PM172 has an embedded logical controller that runs different actions in
response to user-defined internal and external events. Unlike a PLC, the
meter uses a simplified programming technique based on setpoints that
allows the user to define a logical expression based on measured analog
and digital values that produce a required action.
