Programmable Signal Inputs
The UPS incorporates two programmable signal inputs (see Figure 47 on
page 89). 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 51 on page 94 for the polarity and verify these connections if polarity
control is required.
Table 7 shows the programmable settings for the signal inputs.
Table 7. Programmable Signal Inputs
Signal Description
on generator If active, the High Efficiency setting is disabled (BladeUPS 12i
model only) and battery tests are disabled.
charger off If active, the battery charge function is disabled. In a utility
power outage, the discharge of batteries is supported.
on/OFF 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.
force bypass If active, the UPS is forced to static bypass operation
regardless of the bypass status.
ext battery breaker If active, the UPS knows that the external batteries are
disconnected.
empty Not in use (default).
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.
