Replacing Output Modules

The TimeProvider supports up to four Output modules on the shelf, and up to four additional Output modules on the Expansion Panel. A variety of Output modules is available to support different wiring schemes (see Making Output Connections, on page 66, for a description of the available Output modules).

To remove an Output module:

7. Disable the outputs on the Output module by issuing the command:

ED-EQPT::OUTg:::OUTSTATE=DISABLE;

where g is the output group you are disabling (A, B, C, or D)

8.Attach a wrist grounding strap and connect it to the TimeProvider chassis.

9.Remove the output connections.

10.Remove the Output module by loosening the captive screws and pulling the module off the shelf.

Warning: To avoid possible electrostatic damage to the Output module, place it in a static-free bag or on a static-free surface.

11.Place the module in a static-free bag or on a static-free surface.

To install an Output module:

1.Install the Output module on the connector on the shelf and tighten the captive screws.

2.Install the output signal connections to the Output module. After you install the connections, you can remove the protective ground strap from your wrist.

3.Enable the outputs on the Output module by issuing the command:

ED-EQPT::OUTg:::OUTSTATE=ENABLE;

where g is the output group you are enabling (A, B, C, or D)
