for operating a blocks of dedicated conditioner modules, without a base unit!)
In conjunction with a connected base-unit, deactivation is not accomplished directly but instead always
by means of a "Shutdown"-signal communicating with it. This provides both the ability to stop the
measurement in a controlled way and reliable conclusion of data saving to the device, and thus total
data integrity.
In consequence, the following possible scenarioslead to activation of the Power-Handle and the module
block connected to it:
The base unit whose push button is pressed is connected (regardless of the base-unit's Remote
terminal!),
a push button connected to the Power-Handle's Remote terminal ("SWITCH") is pressed,
an external power supply (LEMO) is applied and a switch connected to the Remote terminal is
closed ("SWITCH1"),
anexternal power supply (LEMO) is applied, and additionally, a PoE voltage higher than 3V is applied
at the Power-Handle's EtherCAT terminal ("IN").
The power supply module switches itself off under the following conditions:
The base unit is connected and after having been active it has been powered down and has
deactivated itself. This in turn may be initiated in particular when, after an outage of the external
power supply, the UPS buffer duration has elapsed and the base-unit has received a "Shutdown"-
command from the Power-Handle.
No base-unit is connected but only conditioning modules, and the voltage level of a PoE voltage
applied at the Power Handle's EtherCAT terminal ("IN") falls to below 2V.
No base-unit is connected; sudden deactivation upon elapse of the UPS buffer duration in case of
UPS operation, or in response to pressing the pushbutton or throwing the Remote-terminal's
switch.
The Reset button on the front panel is pressed.
During operation, a base-unit connected to the power supply unit receives a Shutdown-command if:
a pushbutton connected with the module's own Remote terminal is pressed,
a switch connected with the module's own Remote terminal is opened, or
in case of UPS operation, the UPS-bufferduration has elapsed.

1.4.7 Charging the internal battery of a Power-Handle having UPS-functionality

System power supply units (Power Handles) having additional UPS functionality, i.e. an internal buffer
battery, only charge up the battery if they are switched on. This is by intentional design, in particular for
purposes of in-vehicle applications, in order to prevent accidental draining of a vehicle battery due to the
considerable current draw for charging.
Therefore, if a Power-Handle having a UPS battery is to be charged separately from its measurement
system, for instance in preparation for the buffer or in order to refresh it, by means of an AC/DC adapter,
while the rest of the system remains in the vehicle, then this Power Handle module must be activated in
"Stand Alone" mode. Since it doesn't have its own manual main switch, this can be accomplished by
means of its REMOTE-terminal's remote control signals, for instance by bridging Pins 1 and 2.
