Programmable Signal Inputs

The UPS incorporates two programmable signal inputs (see Figure 46 on page 77).
Use of non-polar (relay) control input is recommended. The pins must be shorted with
maximum resistance of 10 ohm in order to activate the specific input.
NOTE See Figure 50 on page 81 for the polarity and verify these connections if polarity control is required.
Table 8 shows the programmable settings for the signal inputs.

Use the programmable signal inputs to emulate some of the features usually seen on
larger three-phase systems. For example:
S
Configure the signal from a smoke detector or water leak detector to shut down
the system.
S
Configure a vibration sensor or air conditioner sensor to shut down the system.
S
Set actions for alarms from a generator, such as disabling the charger for an
undersized generator or shutdown for a failed generator.
S
Configure an ATS (automatic transfer switch) sensor to transfer the system to
Bypass mode.

Description
Not in use (default).
These alarms can be activated separately or at the same time with other
building alarms.
NOTE Building alarms are local only to the UPS.
If active, the High Efficiency setting is disabled (BladeUPS 12i model only)
and battery tests are disabled.
If active, the UPS knows that the external batteries are disconnected.
If active, the UPS transfers the load to bypass when the bypass voltage,
frequency, and phase rotation are within the allowed limits.
If active, the UPS is forced to static bypass operation regardless of the
bypass status.
If active, the UPS output turns off regardless of the mode of operation.
Auxiliary power, communication, and rectifier/battery charger remain
functional. Restart is initiated immediately when this signal is inactive.
If active, the battery charge function is disabled. In a utility power outage,
it supports the discharge of batteries.
