Command TAR SH1 10 is executed in the following example:
=>TAR SH1 10 <ENTER>
79RS 79CY 79LO SH0 SH1 SH2 SH3 SH4
0 0 1 0 0 1 0 0
0 0 1 0 0 1 0 0

79RS 79CY 79LO SH0 SH1 SH2 SH3 SH4
0 0 1 0 0 1 0 0
0 0 1 0 0 1 0 0
=>
Note that Relay Word row containing the SH1 bit is repeated 10 times. In this example, the
reclosing relay is in the Lockout State (79LO = logical 1), and the shot is at shot = 2 (SH2 =
logical 1). Command
TAR 31 will report the same data since the SH1 bit is in Row 31 of the
Relay Word.
TIM Command (View/Change Time)
TIM displays the relay clock. To set the clock, type TIM and the desired setting, then press
<ENTER> . Separate the hours, minutes, and seconds with colons, semicolons, spaces, commas,
or slashes. To set the clock to 11:30 PM enter:
=>TIM 23:30:00 <ENTER>
23:30:00
=>
Note: After setting date or time, allow at least 60 seconds before powering down the relay or
the new setting may be lost.
