Dry Contact - Configure

Usage:

The contacts are configured by using the UPS View software package.

User Programmable Remote Input Contacts

Each of the six user programmable remote input contacts has an operating parameter. The operating parameter is used in order to configure that contact.

The following list of functions can be assigned to the remote input contacts by entering the parameter in the operating parameter for the associated remote input. The default function assignment is listed in Table 2.

The User Programmable Remote Input Contacts must close in order to signal the proper function. The User Programmable Remote Input Contacts must have the following characteristics: form 2 normally open and free of voltage.

User Programmable Remote Output Contacts

Each of the six user programmable remote output contacts has an operating parameter that is used to configure that contact. The functions that are listed in Table 3 can be assigned to the remote output contacts by entering the parameter in the menu for the operating parameter for the associated remote output. The default function assignment is listed in Table 4.

Each User Programmable Remote Output Contact provides a Form C connection. The contact is rated for 3 amperes.
