Changing Relay Module Settings - Sensor Electronics SEC Millenium Series Instruction And Operation Manual

7.0 Changing Relay Module Settings

The SEC 3500 OI supports the SEC Relay Modules for controlling important external
devices such as emergency control valves, indicators, audible alarms, etc. based on Gas
levels reported by individual SEC 3100 devices, entire zones, or all zones (global) on the
entire Modbus controlled by the particular SEC 3500 OI. Alarms can be mapped to
individual Relay Module coils using Boolean logic. For instance; a single device alarm
level can be mapped to a single Relay Module coil, or multiple alarm levels from a single
device can be logically combined together to control a single coil. Essentially the
combinations are almost limitless.
Relay Module Coil Mapping Considerations:
• A single device can be mapped to multiple Relay Module coils.
• Multiple alarm levels can be logically combined together to control a Relay
Module coil.
• Multiple devices combined in a single zone can be mapped to multiple coils.
• Multiple zones (global) can be mapped to multiple coils.
Coil Configurations/Considerations:
• Normally Open or closed (constantly energized or de-energized).
• Latching Modes; Normal (off), Latching (on), or Audible (in HMI version
2.1.0080+).
• They can individually be manually forced on or off whether or not they have
been configured for control by a device, zone or a global (all devices/zones)
alarm set.
