The Access Level 2 commands primarily allow the user to change settings or operate
relay parameters and output contacts. All Access Level 1 commands can also be
executed from Access Level 2. The screen prompt is: =>>
ACC
Enter Access Level 1. If the main board password jumper (JMP6A) is not in place, the
relay prompts for the entry of the Access Level 1 password in order to enter Access
Level 1.
BAC
Enter Access Level B. If the main board password jumper (JMP6A) is not in place,
the relay prompts for the entry of the Access Level B password in order to enter
Access Level B.
BRE
Breaker report shows trip counters, trip currents, and wear data for up to three
breakers.
BRE R n
Reset trip counters, trip currents, and wear data for Breaker n (n = 1, 2, 3, A).
BRE W n
Pre-set the percent contact wear for each pole of Breaker n (n = 1, 2, 3).
CEV n
Show compressed winding event report number n, at 1/4-cycle resolution.
Attach DIF for compressed differential element report, at 1/4-cycle resolution.
Attach R for compressed raw winding data report, at 1/16-cycle resolution.
Attach Sm for 1/m cycle resolution. (m = 4 or 8 for filtered data; m = 4, 8, 16, 32, or
64 for raw data)
CLO n
Assert the CCn Relay Word bit. Used to close Breaker n if CCn is assigned to an
output contact. JMP6B has to be in place to enable this command.
CON n
Control Relay Word bit RBn (Remote Bit n; n = 1 through 16). Execute CON n and
the relay responds: CONTROL RBn. Reply with one of the following:
SRB n
set Remote Bit n (assert RBn)
CRB n
clear Remote Bit n (deassert RBn)
PRB n
pulse Remote Bit n [assert RBn for one processing interval (1/8 cycle)].
COP m n
Copy settings and logic from setting Group m to Group n.
DAT
Show date presently in the relay.
DAT m/d/y
Enter date in this manner if Date Format setting DATE_F = MDY.
DAT y/m/d
Enter date in this manner if Date Format setting DATE_F = YMD.
EVE n
Show standard event report number n, with 1/4-cycle resolution.
Attach S8 for 1/8-cycle resolution.
EVE D n
Show digital data event report number n, with 1/4-cycle resolution.
Attach S8 for 1/8-cycle resolution.
EVE DIF1 n
Show differential element 1 event report number n, with 1/4-cycle resolution.
Attach S8 for 1/8-cycle resolution.
EVE DIF2 n
Show differential element 2 event report number n, with 1/4-cycle resolution.
Attach S8 for 1/8-cycle resolution.
