60Inputs/Outputs Menu8.1 Configure snooze8.2 View inputs/outputs8.3 RelaysConfigure snoozeIn the event of an alarm, the “snooze” button stops the instrument buzzer and returns all the relays in theinstrument to their normal state during a "snooze time".Enter the snooze time in seconds and press OK.View inputs/outputsThis view option displays the state of the 3 alarm relays (on or off), and the analog output current valuefor each.RelaysThere are three measurement alarm relays and one system alarm relay for the instrument. These relaysare configurable as either standard or custom events through the instrument menu.• An alarm relay can be activated or deactivated• When the alarm is OFF, it is activated,• When the alarm is ON, it is deactivatedAll the relays are activated as soon as the instrument is ON (but alarms are OFF). When the instrumentis OFF, the relays are deactivated, thus in this state, all alarms are ON. The logic "Relay deactivated =Alarm ON" has been chosen for this safety reason.When the main board does not communicate with the measurement board for more than 30 seconds, themeasurement board switches all the alarm relays and the analog output to the alarm state.Relays configuration The three relays can be triggered by several standard events, or acombination of events (custom). The relays output can be used to turn on abeacon, horn or PLC. Refer to Connections to electronic boards on page 31.Note: Relays can be set to Normally Open [NO] or Normally Closed [NC] bychanging the jumper positions on the measurement board. Refer toMeasurement alarm relays on page 32.• Select a standard event in the rolling list• If “Custom event” has been selected, it has to be configured by touchingthe configure button• Press on the text box to open the selection menu (rolling menu). Selectthe events that must trigger the relay, and press OK.Proceed in the same manner for other events that should trigger the relay.Test channel relays The three measurement alarm relays can be manually activated for testingpurposes:• Select Relay On, Off or Not under test.See note regarding the relays below. “Not under test” means the relay is inoperating mode, and it will be triggered normally.Note: A relay set to NO will close when activated (On), but a relay set to NCwill open. Refer to Measurement alarm relays on page 32.Test system relay Similarly, the system alarm relay can be manually activated for testingpurpose.• Select Relay On, Off or Not under test.Note: In both the Test Channel Relays and Test System Relay options above, once the tests have beencompleted press Cancel to exit the screen. At the same time, this will reset all relays (including the systemrelay) back to a status of “Not under test”.
