1.5 Alarm relay
BLR-CM is equipped with an alarm relay to signal proper function of the system. The alarm relay has one C/O contact.
The common point is terminal M.
Between the terminals M and MO is the breaking contact. This contact is closed in alarm condition or when BLR-CM is
disconnected from voltage.
Between the terminals M and MS is the closing contact. This is closed in proper condition of the system.
The breaking capacity is 3A / 250V AC.
The circuit diagram is depicted in chapter 3.9!
1.6 Digital input
1.6.1 Digital input for alarm-system
BLR-CM is equipped with a digital input for AC-voltage for alarm-system (50-250V AC, terminals DI1.1 and DI1.2). Digital
input can be active high or active low. The function can be programmed in the menu "SETUP / ALARM / DI INPUT" (2.5.7)
More details for the programming can be found in chapter "ALARM". See circuit diagram in chapter 3.9!
1.6.2 Digital input for data-logger synchronisation (only option –DM)
BLR-CM with option –DM is equipped with a digital input for DC voltage (10-30VDC, terminals DI0.1 and DI0.2). More
details can be found in chapter 2.5.9. The circuit diagram is depicted in chapter 3.10!
1.7 Digital output
BLR-CM is equipped with one digital output (terminals DO1 and DO2). This output is a potential-free closing contact.
The breaking capacity is 5A / 250V AC. The function of this output can be programmed in the menu "SETUP / ALARM"
(chapter 2.5.7). The circuit diagram is depicted in chapter 3.9!
