Alarms And Warnings - Pentax IPFC 109 Manual De Instrucciones

The device that has been switched on first is the MASTER
device of the unit (as indicated by the blinking SET LED),
while the second device is called SLAVE.
To start/stop the unit in COMBO mode, press PLAY or
STOP from the MASTER device (blinking SET LED).
Pressure must be adjusted always from the MASTER de-
vice.
In the event one of the two units fails or triggers an alarm,
the other unit restarts operation after 1 minute from the
stop, guaranteeing continuity of service.
The device can alternate the operation of the pumps to
maintain the same operation hours and, therefore, their
wear, facilitating programmed maintenance operations.

11. Alarms and warnings

•
LED Off: No power supply
•
LED On: Correct power supply (1 x 230 VAC +/-
15%)
•
Blinking Red LED: under-voltage
•
Blinking Red and Yellow LEDs: over-voltage
•
LED On: motor on.
•
Pressure control: pump operation at the
required pressure.
•
Fixed frequency / external frequency: pump
operation at fixed frequency.
•
Blinking LED: Pressure control pump with measured
pressure different from the required pressure.
The blinking frequency of the LED increases when
the required pressure is about to be reached.
•
Blinking LED: EPIC in constant pressure regulation
mode and regulation buttons deactivated.
The SET LED switches on and regulation is
activated by holding key + down for three seconds.
•
LED off: EPIC in manual mode at fixed frequency or
external frequency
In COMBO operating mode, the SET LED is off in
the SLAVE device.
•
LED On: regulation activated.
The ALARM LED indicates an alarm based on a variable
number of blinks followed by a three-second pause.
•
1 Blink: no water; automatic restore attempt after 5-
10-20-40-80 minutes followed by definitive alarm
(restart is possible only after deactivation).
•
2 Blinks: maximum motor current (consumed current
higher than the set threshold).
•
3 Blinks: sensor alarm (no connected and efficient
sensor, incorrect connection or output current lower
than 2 mA).
•
4 Blinks: thermal alarm (NTC heat sink temperature
higher than 70 ° C).
•
5 Blinks: maximum inverter current alarm (restart is
possible only after deactivation).
•
6 Blinks: master conflict alarm during COMBO
operation (switch one of the inverters with triggered
alarm off).
•
7 Blinks: no Master. Wait until the Slave becomes
Master (it may require up to one minute)
•
8 Blinks: No control communication - power side
(this alarm is normally triggered upon activation for a
few seconds)
•
Fast blinks without intermediate pauses: Digital
puts open.
