Rotary Coding Switch, Backup Time; Jumper Variants - Siemens SITOP UPS1600 Equipment Manual

2.3.1.2

Rotary coding switch, backup time

The buffer time is set using the rotary coding switch ⑧ on the device front between
30 seconds and MAX in steps of 0.5 minute (30 s), 1 minute, 2 minutes, 5 minutes,
10 minutes, 20 minutes and MAX. The MAX setting means that buffering is realized for as
long as possible. The device only shuts down when the battery has discharged down to the
stop buffering voltage. Condition when delivered is 5 minutes.
The rotary coding switch has an additional setting OFF (see following diagram). If this is
selected and the additional threshold rotary coding switch is not set to REN, then buffering is
deactivated.
If the buffer time is to be set using the software (only for devices with an interface (...-1AY0,
...-2AY0)) (possible setting range, see Section Parameterizing SITOP UPS1600 (Page 92)), the
rotary coding switch for the connection threshold must be set to REN (see Section Rotary
coding switch, switch-in threshold (Page 34)).

Note
It is only permissible to operate the rotary coding switch using an insulated screwdriver.
2.3.1.3

Jumper variants

On/Off (pin 9)
The wire jumper on the signal connector ④ between pin 9 and pin 10 is used to
enable/disable the buffer mode (see Figure 2-7 Signal connector (Page 28)).
Buffer mode is only possible if the ON/OFF wire jumper is closed. The ON/OFF wire jumper
has priority over the position of the switch-in threshold rotary coding switch. Delivery state:
Wire jumper is closed between pin 9 and pin 10.
As a consequence, buffer mode can be enabled or prevented using a floating contact (e.g. a
contact in the plant or system). The contact is switched instead of the ON/OFF wire jumper.
Note
The contact in the switched-on state must have a resistance of < 10 Ohm,
contact load must be a minimum of 15 V / 5 mA.
Note
The external circuit must meet the requirements relating to SELV (ES1) circuits according to
EN62386-1.
