Remote Shutdown
The R1 and R2 screw terminals are used for the remote shutdown function. When remote
shutdown is active, the UPS does not switch over to the buffer mode in the event of a supply
voltage failure; the device switches off. The rechargeable battery module is charged when
the supply voltage is reconnected, but the device remains switched off until R1 and R2 are
shorted. To activate remote shutdown, do not short-circuit the terminals.
For normal Click 203 operation—the UPS switches over to buffer mode in the event of a
supply voltage failure—remote shutdown should be deactivated.To deactivate remote shut-
down, short-circuit the terminals (i.e. with a plug-in bridge).
On-device Configuration
The Click 203 has several features for monitoring and configuring the operation of the
module.
The buffer time selector switch, marked with numbers around the circumference, can be
used to set how long the device will remain in buffer mode before automatically turning
off. Insert a small screwdriver into the hole and twist until the arrow in the screw head is
pointing to the time you want. The switch has times from half a minute to thirty minutes,
or you can set it to remain on continuously by turning the dial to the ∞ sign. If the switch
is set to the continuous option, the Click 203 will run until the battery is discharged and
then turn off.
The potentiometer, marked "22.5-28.5 V DC, " can be used to set the DC output voltage.
Insert a small screwdriver into the hole and twist clockwise to raise the voltage and counter-
clockwise to lower it. Change this setting only if instructed to do so by Wavetronix Techni-
cal Services.
Signaling Outputs
The Click 203 features three signal outputs: alarm, battery mode and battery charge. These
outputs work in conjunction with the three LEDs to monitor module operation. See the
table below for an explanation of how these outputs and LEDs work.
