Safe Limited Speed Wiring Example

Chapter 10 Safety Configuration and Verification

Configure the Speed Monitoring Relay

You configure the relay using a HIM (catalog number 20-HIM-A3) to set the configuration parameters. You can also use DriveExplorer software, version 5.02 or later, or DriveExecutive software, version

4.01 or later.

The relay is configured in the Safe State. The relay must be unlocked to be configured. If a password exists, you must provide the password to unlock the relay.

Follow these steps to configure the relay.

1. Unlock the relay configuration, if it is locked, by setting the P5

[Lock State] parameter to 0 (Unlock).

2. If an error occurs, you need to enter the password, by using the

P1 [Password] parameter.

3. Place the relay in Program mode by setting the P6 [Operating

Mode] parameter to 0.

If you are using DriveExplorer or DriveExecutive software, you will see the P10 [Signature ID] parameter value change to 0.

IMPORTANT

When the relay is in Program mode, the P69 [IO Diag

Status] parameter is not updated or refreshed.

4. Edit parameters to meet your system configuration specification and risk assessment requirements.

5. When you are finished editing parameters, set the P6 [Operating

Mode] parameter to 1, which puts the relay into Run mode.

A configuration Signature ID is generated.

6. Record the configuration Signature ID from the contents of the

P10 [Signature ID] parameter.

7. Enter the password, if required.

8. Set the P5 [Lock State] parameter to 1 (Lock).
