Ferrogard GS1 & GS2
Description
除夕守岁
The Ferrogard range of magnetically actuated safety switches offers Non contact reliability together with tolerance to misalignment. They are designed to be installed so that when a guard door is
opened, the action of the magnetic actuator being removed from the switch opens the N.C. safety contacts which are intended for the isolation of control power to a machine primary control element.The GS1 and GS2 are designed for heavy duty applications. The GS1 is houd in a stainless steel or brass housing. The GS2 offers the same characteristic as the GS1, but in an Ex housing for hazardous locations.
Unlike some magnetic switches the Ferrogards have protected safety contacts to help ensure that they do not fail to danger.
All Ferrogards have internal non-rettable overload protection on the safety contact. They should be protected by an external fu rated as shown in the specifications table.
See the Explosion Proof ction on page 16-1 for more information on the EX version of the Ferrogard GS2.

Ferrogard Applications
Application Details
Encapsulated in the Ferrogard is a unique high power industrial reed, capable of switching up to 15A. The need switch is de-rated by a non rettable overload protection fu. On prenting the actuator to the switch, the high intensity magnetic field from the actuator caus the contacts to clo. On removing the actuator (opening the door), the safety contacts open.
Mounting Example 1
Door Clod, Machine RUN
Door Opened, Machine STOP , Door Covering Switch
Note: Whenever possible, the units should be mounted so that no access can be obtained to the switch when the guard door is open, thus preventing attempts to defeat the safety system.

Application Details
Typical Applications
Note: Under the requirements of the Machinery Directive all machinery must undergo risk
asssment to determine the necessary level (or category) of the safety related control system or ha
zard avoidance measures. While the Ferrogard complies with the requirements of EN1088 it may not be suitable for all types of machinery or environments. Where magnetic materials are prent or if it is foreeable that through machine function or u. Ferrogard operation by magnates other than the supplied actuator is possible, then u of an alternative Allen-Bradley Guardmaster switch is recommended. Other Non contact options include: Ferrocode (which utilizes additional coding techniques preventing them from being overridden by simple means). Alternatively additional measures may be taken to prevent the Ferrogard being easily bypasd. Consideration should be given to the recommended installation example given in the instructions and tho in EN1088.
Note: Removable guards using Non contact switches may require two switches, one at either side of the guard, or the u of a flap to prevent initial lifting of the non-interlocked edge.
