The Guardian line
safety rope pull switches and grab wire pull cords are designed to be mounted
on machines and sections of conveyors which cannot be protected by guards.
In contrast to
traditional mushroom head type emergency stop buttons, Grab Wire Safety Rope
Switches can initiate the emergency command from any point along the installed
rope length and provide robust Emergency Stop Rope Pull protection for exposed
conveyors or machines.
In combination with
a dual channel safety monitoring relay, IDEM’s range of safety rope pull
switches and grab wire pull cords can be used as emergency stop devices,
monitored for up to PLe in acc. with ISO13849-1.
All IDEM safety rope
pull switches conform to ISO 13850 and IEC 60947-5-5 and have a positive
mechanical linkage between the switch contacts and the wire rope. The rope pull
switches have wire breakage monitoring.
On pulling the rope,
the safety contacts are positively opened and the auxiliary contacts are
closed. The safety rope switches are mechanically latched and can then only be
returned to the operational condition by pressing the blue reset button as
required by ISO 13850.
An optional 2 colour
LED indicator is available to enable switch status to be viewed from a
distance.

保護線安全拉繩開關和抓斗線拉繩被設計安裝在不能被保護的機器和傳送帶部分。
與傳統(tǒng)的蘑菇頭型緊急停止按鈕相比，抓斗鋼絲繩安全繩開關可以啟動緊急命令沿著安裝的繩子長度的任何點，并為暴露的輸送機或機器提供強大的緊急停止繩拉保護。
與雙通道安全監(jiān)控繼電器相結(jié)合，IDEM的安全拉繩開關和抓斗電線拉繩可作為緊急停止裝置，監(jiān)控高可達PLe。
ISO13849-1。
所有IDEM安全拉繩開關符合ISO 13850和IEC 60947-5-5，并在開關觸點和鋼絲繩之間有積極的機械連接。
拉繩開關有斷線監(jiān)控。
拉繩時，安全接點積極打開，輔助接點閉合。
安全繩開關是機械鎖存的，只有按下ISO 13850要求的藍色復位按鈕才能恢復到操作狀態(tài)。
一個可選的2色LED指示燈，使開關狀態(tài)可以從遠處查看。
