The manufacturer gives the warranty of twelve (12) months to the products and thereto related

firmware from commissioning or eighteen (18) months from the date of delivery of the products

which ever occurs first.

The manufacturer is during the warranty period responsible for defects in the products and

thereto related firmware resulting from faults in material, design or workmanship. The

manufacturer’s only obligation under this warranty is to, at its sole discretion, either to replace

the products and/or thereto related firmware or to repair the defective products. The

The manufacturer gives no other warranties whatsoever for the products than the warranty set

out in this section and thus the warranty given in this section sets forth the warranty given by the

manufacturer in its entirety.

1.5 Limited Liability

The manufacturer shall under no circumstances be liable for loss of production, loss of profit,

loss of use or any other consequential damages and/or indirect losses, whatever their cause

may be. In case claims based on product liability are brought against the Manufacturer for which

claims the manufacturer may be liable, the manufacturer’s liability is limited to the extent

normally covered under normal product liability insurances.

The buyer shall compensate the manufacturer to the extent that the manufacturer might be

liable to pay damages as a result of claims based on product liability according to paragraph

above.

1.6 Environmental Statement

The manufacturer uses ISO14001 environmental certified processes and materials to

manufacture products. The manufacturer undertakes to arrange for the recycling and scrapping

of the products that are returned to the manufacturer by the buyer and/or the products that are

received by the Manufacturer in connection with maintenance services performed as a result of

that repairing of the products is deemed by the manufacturer to be inappropriate.

The manufacturer will charge a scrapping fee from the buyer according to the manufacturer's

price list in force from time to time. No scrapping fee will, however, be charged for products that

4.2 Configurable I/Os

Control unit contains inputs and outputs or, in other words, I/O pins of many different types.

There are, for example, outputs which source current and outputs which sink current.

Furthermore, there are I/O pins which can be used as inputs or as outputs at the control of the

application programmer.

The following table contains a summary of configurable I/O pins in Epec 5050 control unit:

4.3.1 PWM/DO/DI_Type005

Output (PWM/DO)

•This kind of pin is a current sourcing output with a pull-up selection

•In other words, the pin connects the load to a positive supply voltage

•When the pull-up is selected, it will affect two output pins (the pairs are indicated with upper

case characters in the pin table's Group column in section Pinout Map).

•This pull-up feature is for open load detection when the pin is used as an output.

•These outputs have a switching element called a smart FET. It has integrated features to

protect itself and also the external pin, wiring and actuator.

•These outputs are capable of generating pulse width modulated (PWM) output signals.

•When used as an output, the input feature indicates the output FET's state

Before the supply voltage can be connected to an output pin, the related power

switch must be switched on as well.

Input (DI)

•This pin can be used as a digital input (DI)

•A pin of this type can also be used as an input by using the output state monitoring feature.

•In this case, the output functionality of the pin must be kept in the off state.

•It must be taken care in system design that the output unintentionally switching to on state

causes no harm to the system.

•This pin can be used also with NPN-type sensors – sensors with open collector/open drain.

Note 1: The frequency of a (PWM) Pulse Width Modulation is = 1 / Period

Note 2: The duty cycle is defined as the percentage of digital ‘high’ to digital ‘low’ signals

present during a PWM period.

Note 3: The PWM resolution is defined as the maximum number of pulses that you can pack

into a PWM period.

Note 4: tC denotes the software cycle time.

Note 5: Current limit for short circuit protection to protect cabling and to limit internal power

dissipation.

Note 6: Exceeding the max value might cause damage to input.

Note 7: The maximum output current depends on the load, PWM frequency and temperature.

Note 8: The pulse width must be greater that the software cycle time. For example with 50/50

pulse ratio, the pulse frequency is 1 / (2*pulse width)

Note 9: When the limit is exceeded, the output voltage circuit starts to limit the current by

switching the output voltage. The switching does not effect the application software

Note 10: When the frequency increases, the actual duty cycle may be bigger than the value that

has been set.

Note 11: Overload conditions
