3. Resetting Once energized alarms can be reset in two different ways automatically or manually non latching or latching In non latching mode the alarm outputs will de energize on their own when the process variable drops below the limit value In the latching mode they stay energized even if the process variable drops below the limit To reset the energized outputs in latching mode first make the display indicate the limit that needs to be reset e g LT2 by pushing the DATA key as described above under Displaying Next while keeping the DATA key pushed go on to push the RESET key The respective alarm output will de energize and the system will indicate so by displaying RLY RST Selection of latching or non latching Page 19 mode outputs is done during setup Electro Mechanical Relay Option CN1511 units can be ordered with either open collector outputs or electro mechanical relays for process limit alarms Check model number printed on the unit for option If ordered with relays then these relays are programmed during Setup to operate as Normally Open NO or Normally Closed NC The default setting is Normally Open Each of these limit relays provides a switched output whenever a limit is reached The maximum rating for 120Vac unit is 120Vac 0 5 amp or 28 Vdc 1 0 amp Figure 4 Electro mechanical Relays Hookup Example SWITCHED OUTPUTS Li
