The Bypass Control allows the operator to enable a timed bypass from the display. When the bypass is enabled it can be used to diable shutdown conditions within the PLC code as required.
When the bypass is activated the icon on the display turns yellow. When the bypass time counts down to below 15 minutes the icon turns red and flashes.
The bypass time can be extended by the operator pressing the ON button.
The bypass can be switched OFF by the operator, or automatically when the bypass timer expires.
The block provides outputs which can be used to alarm the bypass is expiring and when it is enabled.
The time that the bypass can be active for is an Engineering paramter which can be adjusted (when logged in with security [C]) on the second page of the popup.
