User Manual 

•

 

Via a digital input when configured as "slot disarm" which is described in 
Configuring Digital Channels chapter. 

 

Important - If a digital input was configured for slot disarm, then the new 

configuration to be downloaded/synchronized must have the same digital input 
configured as "slot disarm". 

•

 

Via Modbus register 257 as described in 

Imported (Write Single) Modbus Register

. 

•

 

Via Ethernet connection from @ptitude Observer.

 

The characteristics of slot disarm: 

•

 

Latching cable fault may be triggered during slot disarm. User must reset latching 
cable faults manually before the release of disarm. 

•

 

Latching cable fault issued before disarm is kept during the slot disarm mode. User 
must reset the latching cable faults manually. 

•

 

Alert relay status is unchanged during slot disarm. 

•

 

Danger relay status is unchanged during slot disarm. 

•

 

Not OK relay status is unchanged during slot disarm. 

 

•

 

Disarm relay on protection module is triggered only for slot disarm mode (not 
channel disarm mode). 

•

 

Protection module and relay module must be configured properly before slot 
disarm is released. 

•

 

Enable/disable of slot disarm does not effect individual channel disarm status.

 

•

 

For the behavior of slot disarm relay, see the table Behavior of Slot Status Relay in 
Relays chapter. 

Rack Disarm 

Rack disarm effects the entire rack. 

Rack disarm can be set through rack disarm input on the rear panel of a protection 
module (labeled as "Disarm"). The location of a rack disarm input is shown in Protection 
Module (PRM) section . Impact on slot level is same as for slot disarm. 

Release of Rack/Slot Disarm after Configuration 

•

 

After a configuration, rack/slot disarm may be released (hence armed) only after 

the system startup. 

•

 

The system startup takes about 30 seconds and is indicated by LED System status 
with green fast flash. 

 

Important - A premature release of rack/slot disarm may cause a missing or 

invalid configuration which results in MCU slaves not getting the new configuration 
and system will then indicate a circuit fault. 

 

Important - Disarm must not be released until the rack/protection module and 

the associated relay module are running with a proper firmware. Be sure to read 
"Protection Firmware Update" chapter thoroughly and understand it.
