• The machine must not be switched on and off intermittently, as this could damage the winding of the motor or the
insulation, due to overheating.
Parameter adjustment
To see the activated alarms go to screen 4 (Fig. 15). To access it, follow the steps in the LC diagram (Fig. 16).
Screen 4 shows the different alarms inside the device and whether they are activated.
The system status can be seen by accessing screen 20 (Fig. 15). To access it, follow the steps in the LC diagram
(Fig. 16). If the fan figure is green, this means it is on. arameters SD2 and SD1 indicate the presence of smoke or a
sensor failure (in this case a wiring failure). Depending on the number of “dampers” the system has (1 or 2) number 1
or number 2 will appear on the screen with a warning of whether they are open or closed.
To access screen 13 (Fig. 15) follow the steps set out in the LC diagram (Fig. 15). The 13 screen provides access
to different parameters: “FIRE SIGNAL”, “DAMPER”, “FAN” and “SAFETY SPEED”.
In the “FIRE SIGNAL” screen (P 16) 2 parameters can be configured: “FIRE SIGNAL LOGIC” allows you to configure
the contactor (NO, NC). The other parameter to be configured is “FIRE SIGNAL DELAY” which allows you to choose
the alarm signal delay time.
In the “DAMPER” screen (P 17) 3 parameters can be configured: “DAMPER TRAVEL TIME” is the “DAM ER” alarm
delay time. If after this time the “DAM ER” does not open, an alarm will be triggered in the equipment. “SMOKE
DELAY” is the delay time from the time the smoke is detected to the time the alarm is activated. “NUM ER OF
DAMPERS” is used to determine whether the system has 1 or 2 “”DAM ERS”.
In the “FAN” screen (P 22) 4 parameters can be configured: “DIFF. PRESSURE MAX” is the maximum configurable
safety pressure and “DIFF. PRESSURE MIN” is the minimum configurable pressure. “DELAY DIFF. PRESSURE,
safety speed” allows you to configure the time period for the equipment to change to the SAFETY S EED if the
maximum pressure configured in “DIFF. RESSURE MAX” is exceeded. “DELAY DIFF. PRESSURE, stop”. This
parameter will stop the equipment if after entering the “safety speed” option and after this time, the pressure fails to fall
to the minimum determined in “DIFF RESSURE MIN.” It is recommended not to modify the parameters established
by the manufacturer.
On the “FAN” screen (P 18) 3 parameters can be configured. “% OVERCURRENT” indicates the “OVERCURRENT”
intensity level with respect to the motor nominal current. “TIME OVERCURRENT” indicates the time during which
“overcurrent” is present. Once this time has passed, the alarm is activated. In this case the “DAM ER” status must be
checked as if it is closed it will lead to an increase in motor consumption. “% LOW CURRENT” indicates whether the
motor is connected. It is recommended not to modify the parameters established by the manufacturer.
In the “SAFETY SPEED” screen (P 19) the % value shown on screen 1 must be configured (Fig. 15) when the
pressure reaches 50 A with the system activated.
External control panel parameters (Fig.8)
The “READY” pilot lamp indicates whether the equipment is ready to operate. The pilot lamp will be on when the main
panel is supplied with power and no alarms are activated.
The “FIRE ALARM” pilot lamp is activated when the equipment receives a fire alarm signal.
The “SMOKE IN DUCT” pilot lamp indicates the presence of smoke in the aspiration duct.
The “COMMON FAULT” pilot lamp is activated when an alarm is activated.
When set to position 1, the “RESET ALARM” selector switch will reset the fire alarm.
For the equipment to function correctly, the “AUTO-MAN” selector switch must be on automatic. The manual position
activates the equipment without the need for the fire alarm to be activated, either to force the system activation or to
perform maintenance checks. In this position, the equipment does not take smoke detection in the aspiration duct into
consideration. This function must only be used by authorised personnel. In the event of smoke entering the pressurised
zone, the responsibility will be that of the fire fighting staff or the maintenance staff who activate this function.
The “MAN.DAMPER” selector switch must be used when the equipment is in the automatic operation mode. If the
system stops due to the presence of smoke in the aspiration duct, the fire brigade may force the manual activation of
the equipment, ignoring the alarm indicating the presence of smoke in the duct. This function must only be used by
authorised personnel. In the event of smoke entering the pressurised zone, the responsibility will be that of the fire
fighting staff or the maintenance staff who activate this function.
