Insulation fault locator
This quick-start guide applies to the EDS440/441-L-CN, W-L-CN,
-S-CN, W-S-CN, EDS441-LAB-4-CN and W-CN devices. It does not
replace the operating manual.
The operating manual can be found on our homepage under
www.bender.de/manuals.
Intended use
The insulation fault locator EDS44… locates insulation faults in
ungrounded DC, AC and three-phase supplies (IT systems).
With an active test current generator (PGH), AC and three-phase
networks in the range AC 0…1000 V and DC networks in the
range DC 0…1500 V can, depending on the PGH type, be monito-
red. An AC residual current in the range 42 Hz…1 kHz, 100
mA…20 A (EDS440) or 50/60 Hz, 100 mA…2 A (EDS441) can be
displayed.
DIN rail mounting
1. Fix one of the mounting clips supplied, either manually or by
means of a tool, into position as shown in the illustration below.
2. EDS…-S-CN only: Attach the BB bus to the device. To do this,
refer to the BB bus mounting instructions supplied.
3. Snap the EDS… device onto the DIN rail.
Screw mounting
1. Fix the two mounting clips supplied, either manually or by
means of a tool, into position as shown in the illustration
below.
2. Drill the mounting holes for the M4 thread according to the
dimensioned drilling template.
3. Then fix the EDS… using two (2) M4 screws.
Network configuration, mains voltage, mains frequen-
cy, leakage capacitance and test current influence the
responsiveness of the EDS system. Please refer to the re-
sponse sensitivity curve in the manual.
Risk of electric shock!
Make sure the system is de-energized before installing
the device. Otherwise there is a risk of electric shock. Fur-
thermore, the electrical installation may be damaged
and the device may be destroyed beyond repair.

Initial commissioning
•Connect the device and the current transformer.
•Connect the devices to each other via the BS bus (EDS…-L-CN)
or BB-Bus (EDS…-S-CN).
•Switch the supply voltage on. The LED "ON" flashes during
power up until the device is ready for operation.
•Set the appropriate BS bus address.
•EDS…-L-CN: by using the EDS rotary switches. The selected
channel address is indicated by a lighting LED.
•Eliminate all possible displayed insulation and device faults via
the ISOMETER® or the EDS…-L-CN RESET button.
•Ensure the EDS… is properly connected.
•A transformer connection test is carried out every 10 minutes.
During each test, the "ON" LED flashes.
To commission the ISOMETER® and the system from the EDS…
and ISOMETER®, refer to the ISOMETER® documentation.
Operation
The EDS…-S can only be operated via the ISOMETER®.
The EDS…-L-CN is operated via the following three keys and oth-
erwise via the ISOMETER®.
Alarm and its effect
General sequence of an alarm message
•The ISOMETER® display indicates a fault and, if applicable, a
measured value or channel.
EDS…-L only:
•The corresponding LEDs light or flash.
•The buzzer sounds intermittently if activated.
•Assigned alarm relays will switch (EDS…-L-CN/-S-CN).
•Assigned digital outputs will switch.
•An alarm message is then sent over the BB bus (EDS…-S-CN)
or BS bus (EDS…-L-CN).
Alarm messages (EDS…-S-CN)
EDS…-S-CN alarm messages are reported via the relays and are
displayed via
the ISOMETER®.
TEST Initiate self test
RESET Reset fault memory
MUTE Disable buzzer for the current alarm message

绪。
•设置适合的 BS 总线地址。
•EDS…-L-CN: 通过使用 EDS 旋转开关。 通过亮着的 LED 灯指
示选择的通道地址。
•通过 ISOMETER® 或 EDS…-L-CN 重置按钮消除所有可能显示
的绝缘和设备故障。
•确保 EDS… 是正确连接的。
•互感器连接测试每 10 分钟执行一次。在每个测试期间，
"ON" LED 灯闪烁。
参考 ISOMETER® 手册，启动 ISOMETER® 和来自 EDS… 和
ISOMETER® 的系统。
工作
EDS…-S 只能通过 ISOMETER® 进行操作。
EDS…-L-CN 可以通过下列三个按键以及 ISOMETER® 进行操作。
报警和它的作用
报警信息的通用排序
•如果需要， ISOMETER® 显示故障，测量值或通道。
仅用于 EDS…-L：
•相应的 LED 灯亮或者闪烁。
•如果启动，蜂鸣器的声音是断断续续的。
•分配的报警继电器动作 (EDS…-L-CN/-S-CN)。
•分配的数字输出动作。
•然后报警信息通过 BB 总线 (EDS…-S-CN) 或 BS 总线 (EDS…-
L-CN) 发送。
报警信息 (EDS…-S-CN)
EDS…-S-CN 报警系统通过继电器报告 并且通过 ISOMETER® 显
示。

报警信息 (EDS…-L)
•绝缘故障：LED „ALARM IΔL“ ( 主报警 ) 和测量通道 LED 灯
所对应的灯同时亮起，就可找到对应的错误。
•如果超过剩余电流阈值：LED „ALARM IΔn“ 和测量通道
LED 灯所对应的灯同时亮起，就可找到对应的错误。
•设备故障，互感器连接故障：
"SERVICE" LED 灯亮。此外，相应通道的 LED 灯闪烁。
•报警信息：受影响的测量通道的通道 LED 闪烁。
•如果几个错误信息同时输出，单独信息可以通过观察报警
或服务 LED 灯或闪烁的通道 LED 来区分。
声音报警 ( 蜂鸣器 ) 可以被分配用于下列故障信息并且用过
MUTE( 静音 ) 按钮停用。
Alarm IΔL、Alarm IΔn、设备故障、连接故障、普通报警、主
动绝缘故障定位。
重置报警信息 (Reset)
要求：重置故障记忆，同时故障不再存在。
执行 RESET 来重置报警。 有 3 中可能性：

•按下外部重置按钮连接到 EDS …
•在 BS 总线或 BB 总线上，从 ISOMETER® 发送 RESET 命令。
按下 ISOMETER® 上的 "ESC" 按钮 退出当前告警信息的显示。
Alarm messages (EDS…-L)
•Insulation fault: Both the LED „ALARM IΔL“ (main alarm) and
the measuring channel LED, corresponding to where the error
was found, light.
•If the residual current threshold is exceeded: Both the LED
„ALARM IΔn“ and the measuring channel LED, corresponding
to where the error was found, light.
•Device fault, transformer connection fault:
The "SERVICE" LED lights. In addition, the corresponding chan-
nel LED flashes.
•Alarm messages: The channel LED of the affected measuring
channel flashes.
•If several error messages are simultaneously output, individual
messages can be distinguished by observing which alarm or
service LED lights or flashes with which channel LED.
The audible alarm (buzzer) can be assigned the following error
messages and deactivated with the MUTE button:
Alarm IΔL, Alarm IΔn, device fault, connection fault, common
alarm, active insulation fault location.
Reset alarm messages (Reset)
Requirement: The fault memory has been activated and the error
is no longer active.
Execute a RESET to reset the alarms. There are 3 possibilities:
•Press the EDS … -L-CN RESET button for at least 1s.
•Press an external reset button connected to the EDS …
•Transmit a RESET command from an ISOMETER® over the BS
bus or BB bus.
Press the "ESC" button on the ISOMETER® to exit the display of the
current alarm message.
