UTPUT DRY CONTACTS
3
THROUGH
6
The connections for output dry contacts 3 through 6 are located in connector group 1 (see Figure 62 and
Table 9). Each of these output dry contacts has 3 pins: COMx, NCx, and NOx (where "x" is the number of
the output dry contact).
When connecting an output dry contact to the external circuit, the connection must be made using the
COMx pin and either the NCx or NOx pin. Use of the NCx pin results in the circuit being Normally Closed.
Use of the NOx pin makes the circuit Normally Opened.
7.2.9.2.4
O
UTPUT DRY CONTACTS IN ACTION
Upon the occurrence of any of the alarm conditions in Table 6, the output dry contact(s) associated with
that alarm (if any) changes state. Output dry contacts 1 and 2 are always Normally Open, so they close
while the alarm exists. Output dry contacts 3 through 6 will change state from open to closed or from closed
to open, depending on whether the NCx or NOx pin was used in connecting the output circuit. When the
alarm condition ceases, the output dry contact reverts to its normal state.

T
ESTING AN OUTPUT DRY CONTACT
An output dry contact that has been associated with an alarm can be tested without actually invoking the
related alarm condition, by pressing the "Test" button at the bottom of the output dry contact screen (see
Figure 45).
Pressing the test button changes the state of the output dry contact to its "non-Normal" condition for about
five seconds.

Setup > SAVE & RESTORE
This set of functions let you save the current UPS settings, and restore them later. This would enable you
to experiment with new settings and then easily return to the previous settings. There is also an option to
restore the factory default settings.
Figure 46: "Setup > Save & Restore" options
7.2.10.1
SETUP > SAVE & RESTORE > SAVE SETTINGS
Saves the current settings of the UPS in non-volatile memory.
7.2.10.2
SETUP > SAVE & RESTORE > RESTORE SETTINGS
Restores to active status the settings that you previously saved in non-volatile memory.
7.2.10.3
SETUP > SAVE & RESTORE >RESTORE FACTORY SETTINGS
This function is displayed only in “Technician” mode. Restores to active status the "factory default" settings
of the UPS. Performing this function does not have any effect on what is saved by the SAVE SETTINGS
function above.
Be aware that using the "restore factory settings" returns the
Centric
settings to what they were when the
unit arrived at your premises. If, for example, you have since added additional power modules, the settings
will not include the additional modules and you must readjust the settings to include the additional modules.
