Using Periodic Timers

The SA300 has 16 programmable timers that are used for periodic recording and
triggering operations on a time basis through the Control Setpoints. When a pre-

programmed timer interval is expired, the timer generates an internal event that can
trigger any setpoint (see

Using Control Setpoints

). The programmable time interval

can be from 1/2 cycle and up to 24 hours.

To configure the device timers, select General Setup from the Meter Setup menu,

and then click on the Periodic Timers tab.

The available options are described in the following table:

Seven timers from Timer #10 through Timer #16 are factory preset and cannot be re-
programmed. They are primarily intended for the use with the Power Quality and
Fault recorders. Other timers can be programmed by the user.
