OPERATING AND PROGRAMMING INSTRUCTIONS
8-37
(18) Error power supply
The 24V power supply is too low (below 20 Volts) or too high (above 40 Volts). Because
this can cause damage to the controller, it has switched all outputs off. The actual power supply
voltage can be checked at any time from the test program menu (see chapter 6.5.4).
(19) Battery empty
When starting up the controller checks if the battery backed-up memory is still ok. If not,
this message will be displayed. This message will only be displayed after start-up. The battery
capacity is enough for 1 year, so it is strongly recommended to replace the battery every year (see
chapter 2.4). The START button must be pushed to reset the message.
(20) Microprocessor restarted
The dryer controller is able to monitor its power supply. If the power supply voltage is too
low, or too high, alarm 18 will be displayed. If the power supply voltage is too low for the
controller to be able to operate the microprocessor will reset itself. This can happen in case of a
sudden, brief voltage drop. If this happens the microprocessor will memorize this and the next time
the controller starts up, alarm 20 will be shown on the display.
(21) Infra-red sensor read error
The presence of an infra-red sensor has been indicated in the machine configuration
parameters (see chapter 6.8, parameter 5), but the controller cannot detect a working infra-red
sensor. This means it cannot determine the batch is dry. The machine is still able to run in case the
infra-red sensor is broken, but it cannot run on automatic drying any more (see chapter 6.4.1,
program parameter 1). So, to be able to run the machine, the sensor should be working or a program
with time-based drying should be chosen.
(22) Humidity sensor read error
The presence of a humidity sensor has been indicated in the machine configuration
parameters (see chapter 6.8, parameter 5), but the controller cannot detect a working humidity
sensor. This means it cannot determine if the batch is dry. The machine is still able to run if the
humidity sensor is broken, but it cannot run on automatic drying any more (see chapter 6.4.1,
program parameter 1). So, to be able to run the machine, the sensor should be working or a program
with time-based drying should be chosen.
(25) Clean lint filter
The dryer controller will monitor input 16 to check if the filter needs to be cleaned (see
chapter 2.3.1, input 16). If the controller detects that the filter needs to be cleaned this message will
be displayed. This message is automatically removed when the filter is clean again or when the
machine is stopped.
(27) Overheating switch
The input for the overheating switches (input 9) is, or has been, in the ‘off’ state while the
heater was switched on. This means that (one of) the overheating switch (es) is activated. When the
overheating switch isn’t active anymore, the message will be reset.
(31) Delayed start in:
Delayed start has been adjusted and the timer for the delayed start is counting down to 0. At
the moment the counter reaches 0, the machine will automatically start (see chapter 6.2)
