10.5 PERFORMING OPERATIONS 10.5.1 DESCRIPTION
The user must be logged in with Control access for access to control operations (not required for DGP with
Modbus protocol). To access control operations, double click on the Operations branch to expand its tree to
select the appropriate operation.
10.5.2 CHANGE PASSWORD
This item allows the user to change the DGP password. The valid password characters are A to Z, 0 to 9, and
space. The factory default password contains one or more characters that are not valid. The communications
password can only be viewed in encrypted form on the MMI; as such, it is IMPORTANT that the user keep a
record of the password in a safe place.
1. To change the password, double-click click Change Password in the Operations branch.
2. Enter the present password then enter the new password.
3. If the new password is valid, it must be entered again.
4. Click the OK button to change the password.
10.5.3 MANUAL TRIP
This item allows the the output relays to be operated manually. Each of the four DGP output relays (94G,
94G1, 94G2, and 94G3) may be operated individually. Note that the relays cannot be operated if the appropri-
ate jumper is installed (see Figure 3–3: DGP POWER SUPPLY MODULE on page 3–4 for the location and
description of the jumpers).
1. To select Manual Trip, click Manual Trip in the Operations branch.
2. GE-Link responds with a selection box showing the four output relays. Select the desired relay and click
OK.
3. The relay operates and GE-Link returns to the Manual Trip item menu.
10.5.4 ENABLE OUTPUTS
This item permits the DGP to energize the relay outputs. Note that the digital outputs cannot be enabled
remotely if the appropriate jumper is installed (see Figure 3–4: DGP MMI MODULE on page 3–5 for the loca-
tion and description of the jumpers).
1. Select the Enable Outputs item in the Operations branch.
2. Click YES to enable the outputs.
10.5.5 DISABLE OUTPUTS
This item inhibits the DGP from energizing any of the relay outputs except for the Critical Alarm output, the
Non-critical Alarm output, the Test Pickup output, and the Test Trip output. Note that the digital outputs cannot
be disabled if the appropriate jumper is installed (see Figure 3–4: DGP MMI MODULE on page 3–5 for the
location and description of the jumpers).
