4.3.6. GUN/ HOSE SEQUENTIAL HEATING: 

This is found under the settings / startup menu. 

The hose on option allows the hose to begin heating after the tank reaches a 

specific temperature below the set temperature. This feature is used to reduce wear on 
the adhesive caused when the adhesive heats up in the hose because the adhesive 
remains in the hose for too long when waiting for the tank to reach the operating 
temperature. 

The temperature range for the hose on option is 0º F to 450º F (0º C to 250º C). 

The option is factory set off. 

The turn on gun option allows the gun to begin heating after the tank reaches a 

specific temperature below the set temperature. This feature is used to reduce wear on 
the adhesive caused when the adhesive heats up in the gun because the adhesive 
remains in the gun for too long when waiting for the tank to reach the operating 
temperature. 

The temperature range for the hose on option is 0º F to 450º F (0º C to 250º C). 

The option is factory set off. 

You can access this parameter with a password level of 2 or higher. 

 

 

Press OK to access the temperature programming screen. Remember to enable 

this option with the switch. 

 

4.3.7. HISTORY: 

This is found under the settings / history menu. 

The errors log saves a list of faults that have occurred in each zone. 

Log change saves a list of all of the configuration parameters and changes. 

The errors log and log change are deleted when the machine is turned off.
