5.10 Lights Management
In the saving mode, the cooler lights are usually off.
For marketing purposes, light delay (Ld) can keep the cooler lights on for a short period after the ems controller
switches to the saving mode.
Marketing mode (Ar) can keep the lights on for the duration of the saving mode.
For more information about the parameters used in lights management
• See “differential (dIF)”
• See “freeze-up protection (dtt)”
5.11 Alarms
For alarm conditions, the ems controller displays the appropriate alarm code and, optionally, sounds an alarm
buzzer. Buzzer enable (b0) defines whether to sound a warning buzzer for alarm conditions. Buzzer duration (b1)
defines the durationof the buzzer for alarm conditions.
For more information about the parameters used in alarms
• See ”buzzer enable (b0)”
• See ” buzzer duration (b1)”
Note
For door open alarms, the buzzer sounds regardless of the buzzer enable (b0) setting.
