isoMED427P-CX
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
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
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
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
提醒
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。
提醒
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。

Intended use
The ISOMETER
R
F
in medical IT systems of AC 70...264 V. In addition, the IT sys-
R
F
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
C

localisation appropriate devices of the EDS series are recom-
mended to be used. Recommended device combinations are
listed in the table on page 11.

In addition to this data sheet, the documentation of the device in-
cludes a sheet entitled "Important safety instructions for Bender

Device-specific safety information
CAUTION
CAUTION
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.
