绝缘监视仪
使用目的
ISOMETER® isoMED427P-CX 监视医疗 IT 系统中的绝缘电阻 R
F，
其范围为 AC 70…264 V。此外，还监视 IT 系统变压器的负载
电流和温度。一旦检测到绝缘故障，内置定位电流发射器能够
及时定位到绝缘故障。
报警和测量值通过 BMS 接口传送给其他总线设备。
对于报警和状态显示，建议使用特殊的报警显示和测试单元。
对于绝缘故障定位，推荐使用EDS系列设备。推荐使用page 11
上列表上的设备组合。
isoMED427P-CX 不需要独立的电源。 最大允许系统泄漏电容
C
e
是 5µF。
通用安全信息
除了这份技术参数外，设备的文件还包含一张题为 “ 本德尔
产品的重要安全说明 ” 的表格。
设备特殊安全信息
功能
在普通操作时，显示屏显示当前测量的绝缘电阻值。向上和向
下按钮用于选择显示当前测量的负载电流的百分比。如果绝缘
电阻下降且低于响应值时，LED AL1 会发出绝缘故障信号。 当
负载电流过高时，LED AL2 会点亮；当超出被监视的 IT 系统的
变压器温度时，报警继电器 K1 会发出全部报警类型的信号。
此外，通过端子 A 提供总线信号，端子 B 用于绝缘故障定位和
报警显示和指示单元。
一旦检测到绝缘故障，内置的故障定位电流发射器立刻进行绝
缘故障定位，前提是在菜单中已经打开 EDS 功能 ( 工厂设置
=off)。在 2 秒的交替时间内，注入正、负定位电流脉冲到被
监视的 IT 系统中，其间有 4 秒的无脉冲暂停时间。
由于安装不专业而造成财产损坏的风险！
如果有超过一台绝缘监视仪连接到带电系统
中，那系统可到会损坏。如果连接数个设备，
那设备不能实现功能并且不会发出绝缘故障
信号。确保在每个带电系统中，仅连接一台绝
缘监视仪。
确保与 IT 系统断开！
当执行绝缘或电压测试时，在测试阶段设备
必须与系统隔离。否则设备可能会损坏。

Insulation monitoring device
Intended use
The ISOMETER® isoMED427P monitors the insulation resistance
RF in medical IT systems of AC 70…264 V. In addition, the IT sys-
tem transformer's load current and temperature are monitored.
Once an insulation fault is detected, the internal locating current
injector allows insulation faults to be localised.
Alarms and measured values are made available to other bus de-
vices via the BMS interface.
For alarm and status indication the use of special alarm indicator
and test combinations is recommended. For insulation fault
localisation appropriate devices of the EDS series are recom-
mended to be used. Recommended device combinations are
listed in the table on page 11.
isoMED427P does not require separate supply voltage. The max-
imum permissible system leakage capacitance Ce is 5µF.
General safety information
In addition to this data sheet, the documentation of the device in-
cludes a sheet entitled "Important safety instructions for Bender
products“.
Device-specific safety information
Function
In normal operation, the display indicates the currently measured
insulation resistance value. The Up and Down buttons are used to
select the display indication of the currently measured load cur-
rent in percentages. If the insulation resistance falls below the re-
sponse value, LED AL1 will signal an insulation fault. LED AL2
lights when the load current is too high and when the tempera-
ture of the monitored IT system transformer is exceeded, alarm
relay K1 signals all types of alarms. In addition, a bus signal is pro-
vided across the terminals A, B for insulation fault locators and
alarm indicator and test combinations.
Once an insulation fault is detected, the internal locating current
injector is activated for insulation fault location, provided that the
EDS function has been switched on in the menu before (factory
setting = off). For a duration of 2 seconds alternately a positive
and negative locating current pulse is injected to the IT system
being monitored with a no-pulse pause of 4 s in between.
Risk of property damage due to unprofession-
al installation!
If more than one insulation monitoring device is
connected to a conductively connected system,
the system can be damaged. If several devices are
connected, the device does not function and does
not signal insulation faults. Make sure that only
one insulation monitoring device is connected in
each conductively connected system.
Ensure disconnection from the IT system!
When insulation or voltage tests are to be carried
out, the device shall be isolated from the system
for the test period. Otherwise the device may be
damaged.

isoMED427P-CX
The isoMED427P can only be operated as BMS slave. That is why
the alarm indicator or the insulation fault locator operates as the
Master. BMS address 1 must always be assigned to the BMS
master.
Automatic self test
The device automatically carries out a self test after connecting to
the supply voltage and later every hour. During the self test inter-
nal functional faults or connection faults will be determined and
will appear in form of an error code on the display. The alarm relay
is not switched over during this test.
Manual self test
After pressing the internal or the external test button for > 2 s, the
device carries out a self test. During this test, internal functional
faults, or connection faults will be determined and will appear in
form of an error code on the display. The alarm relay will be
switched during this test.
Whilst the test button "T" is pressed, all display elements available
for this device are shown.
Functional faults
In case of a malfunction, the relay K1 (11, 12, 14) and all of the
three LEDs flash. An error code appears on the display.
E01 = PE connection fault, no low-resistance
connection between E and KE.
E03 = Measuring current transformer interruption
E04 = Short-circuit measuring current transformer
E05…Exx = Internal device error, contact the Bender service.
Password protection
If password protection has been activated (on), settings can only
be made subject to the correct password being entered (0…999).
Factory setting FAC
After activating the factory setting, all settings previously
changed are reset to delivery status.
Monitoring the IT system transformer
The device monitors the temperature by evaluating the resist-
ance value of a PTC. When a response value of 4 kΩ is reached, an
alarm will be activated indicating overtemperature, the display
shows > °C. Temperature values will not be indicated.
Installation and connection
– The isoMED427P is suitable for DIN rail mounting acc. to
IEC 60715 or for screw mounting, as described below.
In order to avoid transformer overload, load cur-
rent monitoring should be combined with tem-
perature monitoring.
For details refer to the wiring diagram!
Risk of fatal injury from electric shock!
Touching live parts of the system carries the risk of
electric shock. Before fitting the enclosure and
working on the device connections, make sure that
the power supply has been disconnected and the
system is dead. Observe the installation rules for
live working.
CAUTION
DANGER
isoMED427P-CX 只能作为 BMS 从属工作。这就是为什么报警指

自动自检
在连接到电源电压和之后的每个小时，设备会自动执行自检。
在自检过程中，可以确定内部功能故障或连接故障将，并以错
误代码的形式显示在显示屏上。在测试过程中，报警继电器不
会切换。
手动自检
按下内置或外部测试按钮并且持续超过 2 秒，设备会执行自
检。在测试过程中，可以确定内部功能故障或连接故障将，并

器会动作。
当按下测试按钮 “T” 时，设备显示所有可用的元件。
功能性故障
如果发生故障，继电器 K1(11，12，14) 和所有三个 LED 闪烁。
故障代码出现在显示屏上。
E01 = PE 连接故障，在 E 和 KE 之前没有低电阻连接。
E03 = 测量电流互感器中断
E04 = 短路测量电流互感器
E05…Exx = 内部设备错误，联系本德尔服务中心
密码保护
如果已经启用密码保护 (on)， 只有在输入正确密码的情况下
才能设置 (0…999)。
出厂设置 FAC
在启动出厂设置之后，之前更改的所有设置都会重置为运输状
态。
监视 IT 系统变压器
设备通过评估 PTC 的电阻值来监视温度。当达到 4 kΩ 的响应
值时，激活报警显示超温，显示超过 > °C。不显示温度值。
安装和连接
– isoMED427P-CX符合标准IEC 60715 的DIN导轨安装或
下面描述的螺丝安装。
为了避免变压器过载，负载电流监视需要与
温度监视结合。
更详细的内容请参考接线图！
电击造成致命伤害的危险！
接触系统的带电部件会产生电击
