This page describes how the outputs OUT01, OUT02, OUT03 and OUT04 can be used in the POWER33.
These outputs can be used alone dynamic outputs, as Bridge outputs (in pair) . The output offers, in plus, a wiper function (used in conjunction with OUT19):

1-Dynamic alone output

To correctly use the output, we must set a various number of parameters and connect mnemonics.

1.1-Parameters

Parameters, for each output, are classified in different categories :

Category	parameter	Description
General	'Alone' ( full Bridge not used)	When a output is commanded alone and need to use LS function, it's necessary to use it in Push-Pull mode always (Output-Boo stay ON always, and HS_LS used only).
	'Full Bridge'	If this box is checked the output toggle function 'BRIDGE' with the other output associated with it. The outputs OUT01 and OUT02 form the first bridge, and the outputs OUT03 and OUT04 form the second bridge. The operation 'Full BRIDGE' is possible only if the two outputs forming the bridge are free.
	'Enable Wiper'	This option is only available for output OUT01, it can be used to control the operation of the windscreen wiper, this function requires the use of the output OUT19. operating in Wiper function is only possible if both outputs OUT01 and OUT19 are free
	'Current FeedBack'	Must be checked if the user want a feedback of the current in the output.
	'Load Type'	Configure the type of load connected to the ECU output
	'Frequency range'	The output can operate on two different frequency ranges, this parameter determines the range to use 'High' or 'Low'.
	'Frequency'	This parameter determines the frequency for the output, the range of possible values is determined by the previous parameter 'frequency range'. For low range value go from 60 to 500 Hz with a step of 10Hz. For high range value go from 550 to 1000 Hz with a step of 50Hz.
	'Recurr. Period: OUT_CMD'	Set the recurrence time of the Frame 'OUT_CMD' sent by the master ECU to command the slave's outputs. This parameter is common for all the outputs of the POWER ECU.
	'Recurr. Period: OUT_I'	If the option 'Current Feedback' is checked, we must set the recurrence time of the frame 'OUT_I' sent by the POWER to inform about the value of current in its outputs. This parameter is common for all the outputs OUT01, OUT02, OUT03, OUT04, OUT05, OUT06, OUT07, OUT08, OUT19, OUT20, BRIDGE1 and BRIDGE2.
Degraded Mode	'Degraded Mode'	To use or not this output in degraded mode
	'Polarisation 1er cycle'	The output can be activated in HS or LS in the first cycle of the degraded mode
	'1s cycle'	Configure the state of the output in the first cycle of degraded mode (On/Off)
	'Polarisation 2nd cycle'	The output can be activated in HS or LS in the second round of the degraded mode
	'2nd cycle'	Configure the state of the output in the second cycle of degraded mode (On/Off)
Protection Profile	'Auto Calculate'	if this option is checked ,the protection profile parameters values are automatically calculated by ActiGRAF with the Nominal Load.
	'OC_Range', 'OC_MThld','OC_HThld', 'OC_NThld' et OC_Time	These parameters are used to obtain the protection profile, we have two profiles : i-Protection Profile For lamps ii-Protection Profile For motors
Diagnostic	'Authorize MasterMode'	If this option is checked, the output can be controlled in Master mode during a diagnostic session

i- Protection Profile For lamps

This profile will be used if the load attached to the output is one of these types : 'Bulb Load' or 'Resistive Load'. The protection profile for bulb is activated once when the output is turned ON. The output is immediately switched OFF when the current cross up the profile. This profile is described in the graphic below. this graphic is made using the previously cited five parameters.

ii-Protection Profile For motors

As well as for Lamps, except this profile is applied when the load attached is "Motion Motor Load" or "Fan Motor Load". The following graphic describe the behaviour in the motor case :

1.2-Mnemonics

The mnemonics names for Powers ECU IO must applies a set of rules more details.

To activate and use an output,command values must be sent (ON/Off, duty cycle,current ...). This is done by connecting the mnemonics (presenting physical entities of the outputs) to their correspondent variable (functional outputs entities) declared and used in the EA application.
Bellow a description of each mnemonic and its use in the output :

Mnemonic	STraToN Type	Description
'Output_Boo'	BOOL	this is the logical command of the output (activated or not). If this mnemonic is not used (connected) the output is not used.
'HS_LS'	BOOL	is the variable to control the activation level of the output "0" means that the output should be set to 'HS', and the value "1" means that the output should be set to 'LS'. The hardware configuration must be compatible, otherwise the output will not be activated.
'Output_Dyn'	WORD	This mnemonic must be connected to EA application variable containing the value of duty cycle.
'Fault'	BOOL	This mnemonic is used to retrieve a default on the output, in this case the variable connected to it will take the Boolean 'TRUE'
'Fault_type'	BOOL	In the case of a default, the variable connected to this mnemonic will indicate the type of default: 0 : short circuit fault. 1 : open circuit fault.
'Current'	WORD	This mnemonic will only be available if 'current Feedback' is selected. Variable connected to this mnemonic will contain the value of current applied to the output. The current measurement unit is 1 mA. This value is not to be used in case of LS output.
'Equipment'	BOOL	The usage of the variables of default is not active while the variable connected to this mnemonic has its value to 'False' ( more details ).

2-Bridge output

If 'Full Bridge' is selected, we will have two more parameters to configure in the 'General' section . A new section 'failure Parameters' will appears. You have just to change the values in one output, values are correlated between the two outputs forming the bridge.

2.2-Parameters

Category	parameter	Description
General	'Filter Value'	Indicates the coefficient for the function of filtering the current
	'Bridge Breaking Time'	This sets the time taken by the bridge to change direction, if the direction change takes place while output is active
failure Parameters	'Low threshold'	To set the minimum value of current with which the output can operate without a trace default
	'High threshold'	To set the maximum value of current with which the output can operate without a trace default

2.2-Mnemonics

The mnemonics names for Powers ECU IO must applies a set of rules more details.

For a bridge output we have the following mnemonics:

Mnemonic	STraToN Type	Description
'Output_Bridge'	BOOL	This is the variable to control the output (Active or not) must be connected to the EA application variable dedicated to control the Bridge state in the application part. If this mnemonic is not connected then the output will not be used and the mnemonics that follow will have no effect.
'Direction_Bridge'	BOOL	is the variable to control the direction of the bridge. A bridge have two directions: 1-"Forward" : first half-bridge in HS and second in the LS. The variable in this case is set to "0". 2-"Reverse" :is reversed, the first output forming the bridge in LS and HS in the second. In this case the variable takes the value "1".
'Output_Dyn_Bridge'	WORD	This mnemonic must be connected to the EA application variable indicating the dynamic value ( a duty cycle) of the output
'Fault_Bridge'	BOOL	This mnemonic is used to retrieve a default on the output in this case the variable connected to it will take the Boolean 'TRUE'
'Fault_type_Bridge'	BOOL	In the case of a defect, the variable connected to this mnemonic will indicate the type of defect. If the variable is 'TRUE', it is a short circuit default and if it is set to "FALSE" the default is an open circuit.
'CThresholdFail_br'	BOOL	Variable connected to this mnemonic will indicate if the defect is caused by exceeding the hardware threshold in this case the value is 'FALSE', or an overrun of a software threshold that set the value to 'TRUE'.
'Current_Bridge'	WORD	This mnemonic will only be available if 'current feedback' is selected. Variable connected to this mnemonic will contain the value of current applied to the output
'Equipment_Bridge'	BOOL	Default variables usage is not Active , as the value of this variable is set to 'FALSE' ( more details ).

3-Wiper output

This function combines the two outputs: OUT01 to manage the wiper at low speed and OUT19 for the management in high speed. As in the case of operating in 'BRIDGE', parameters and mnemonics are shared . Both OUT01 and OUT19 are considered a single output.

3.1 parameters

Category	parameter	Description
General	'Park position time out'	after an OFF command the windscreen wiper stop at the park position.This parameter set the time out to detect the park position, if the park position is not detected before the expiration of the time out a default is signalled.
	'WiperParkIn'	This parameter indicates the input used to detect the wiper park position. To select an input for wiper park position,check the available option in one off the following inputs: UIN1 : in Logical mode WK1 WK2 FReq1: in logical mode FReq2: in logical mode IN_OUT09: used as input IN_OUT18: used as input
	'Recurr. Period: OUT_CMD'	The value of recurrence of the frame control 'OUT_CMD', this parameter is shared by all the outputs of the calculator.
Degraded Mode	'Wiper Degraded Mode'	This is an analogue Value dedicated to define the output status in degraded mode. There is no consideration for two cycle for the wiper output, so the state will be the same all time (in degraded mode)
Diagnostic	'Authorize MasterMode'	If this option is checked, the output can be controlled in Master mode during a diagnostic session

3.2-Mnemonics

The mnemonics names for Powers ECU IO must applies a set of rules more details.

Mnemonic	STraToN Type	Description
'Output_Wiper'	WORD	This is the variable to control the output. This is an analogue value to define the output state (0: inactive, 1: low speed, 2: high speed).
'Fault_Wiper'	BOOL	This mnemonic indicates a fault detection : open circuit or short circuit on the output "windscreen wiper"
'Fault_Wiper_Park'	BOOL	This symbol indicates a failure if the windscreen wiper fails to regain its park position before the expiration of the park position time out
