– Condition of standby sequence 2, alarm latch and repeated standby mode of standby sequence 2 again: 

switch on, change set temperature, alarm temperature 

[AL1]

 or alarm operation 

[AL-1]

, switch STOP mode 

to 

″Normal″

 mode.

Note: If the alarm operation is set to loop break alarm [LBA], sensor fault alarm [SBA] or heating fault alarm [HBA], only 

the standard alarm [AL-A] and alarm interlock [AL-C] will be displayed.

5.7.3 Alarm Output Lower 

[PAR1 → AL1L]

 and Upper 

[PAR1 → AL1H]

 Limit Value Settings 

Output alarm activation values can be set. The 

[AL1H / AL1L]

 configuration parameters are activated for each 

setting according to the selected alarm operation. The upper / lower limit values are according to the individual 

input specification of the sensor. The lower limit is the reference value for determining burnout of the heating 

element. 

Default setting - Temperature: 1550 / Analog: 100.0

Note: Changing the alarm action or options will reset the settings to the highest or lowest values that will not trigger output 

in the new mode.

5.7.4 Alarm Output Hysteresis 

[PAR4 → A1HY]

Setting the on / off interval for alarm output 1 

(5.7.1 Alarm operation 

[PAR4 → AL-1]

)

. 

″H″

 means the hysteresis 

of the alarm output in alarm operation. It is used to set the interval between the ON / OFF periods of the alarm 

outputs. 

Default setting: 1. It is set to °C / °F / %.

Note: Alarm Output Hysteresis applies the same to Heating error alarm [HBA]. This parameter is not displayed when Loop 

Break Alarm [LBA] or Sensor Fault Alarm [SBA] is selected.

5.7.5 Alarm NO/NC 

[PAR4 → A1N]

Selects the contact type for alarm output 1. The contact mode of the relay can be set in the event of an alarm. 

Default setting: NO.

Setting

NO

Normally open – Stays open normally and closes when there is an alarm.

NC

Normally closed – Stays closed normally, opens only when there is an alarm.

5.7.6 Alarm Output Delay Settings 

[PAR4 → A1ON / A1OF]

The alarm output delay can be set to prevent false alarms caused by faulty input signals due to interference or 

noise. The default setting for both parameters: 0 s.

If there is a preset delay time, the alarm output will not turn on for the preset time. Instead, the front alarm indicator 

flashes every 0.5 seconds.
