JSHT1 A/B Safety Relay
|
The JSHT1 A/B closes two independent relay outputs during a guaranteed maximum time when the inputs are opened.
|
Time Reset
Time reset can prevent unintentional reset of safety system when someone is still in the dangerous area of the machine. During a guaranteed maximum time, one or several PB's for reset must be activated. The reset buttons should be sited in such a way that operatives have a clear overview of the whole area which is guarded. Time reset is made by the combination of a safety relay and the timer relay JSHT1A/B.
Time Bypassing
The JSHT1 can also be used for time bypass of light beams for e.g. autotruck into a dangerous area.
Operation
When the inputs open the output contacts close. The output contacts open when the inputs close or when the time period has expired. The time period is hardwire selectable on terminals T1, T2 and T3. The time given is the maximum time. One or two channel operation is also hardwire selectable.
