own or he can use the automatic calculation in
the menu of the PS 830 (see also section 5.6.1)
Example:
The inflow Q of air through a nozzle with
Example
an inner diameter of 2 mm and an admission
pressure of 2 bar is ca. 1.5 l/s:
3.3 Operation mode "Leakage compen -
sation"
The PS 830 works after the pre purging phase
or without pre purging phase immediately after
the voltage supply in the mode of operation
"leakage compensation".
In this mode of operation will maintain after an
overpressure (at least 0.8 mbar) within the Ex p
cabinet. This cabinet minimum pressure as well
as also a cabinet maximum pressure are pro-
grammable and are monitored constantly.
Leakage losses are compensated by a small
bypass. This bypass is integrated in the valve
and mechanically adjustable (diameter 0.3... 1
mm).

Conformity with standards

The explosionproof control unit PS 830 meets
the requirements of IEC 60079-0, IEC 60079-15
or IEC 60079-31. They have been developed,
manufactured and tested in accordance with
state-of-the-art engineering practice and ISO
9001:2015.

或可以使用PS830菜单中的自动计算（另见
5.6.1节）
例如：
通过内径为2毫米喷嘴流入空气Q Ex'ample，
入场压力为2bar按 1.5升/秒计算
3.3 操作模式"泄漏补偿"
在"泄露补偿"模式下，供电后，PS830在预
吹扫阶段或没有预吹扫阶段即刻工作。
在这种操作模式下，在防爆正压柜内超压(至少
0.8mbar)后将保持不变。 这个柜的最小压力以
及一个柜的最大压力是可编程的，并不断监测。
泄漏损失由一个小旁路来补偿。 该旁路集成在
阀门，机械可调（直径0.3...1毫米）。
3.4 符合标准
防爆控制单元PS830符合IEC60079-0、
IEC60079-15或IEC60079-31的要求，它们
是根据最先进的工程实践和ISO9001：2015开
发、制造和测试的。
