Instructions for

SMC-ARC1


Foreword

The SM-ARC1 control system is specially designed for controlling of the Sprout-Matador A/S automatic pellet mill roller adjustment and can be used as a stand alone or together with a Sprout-Matador A/S pellet mill control. Therefore this manual will describe operation as both stand-alone (mode 2) and from SM32 cs (mode 1). The manual does not describe the mechanical part of the roller adjustment, but only the controlling. Mode 1: SM32 CS The SM-ARC control panel is configured and operated from SM32 CS in connection with a Sprout Matador pellet mill control system, where the roller distance is a formula parameter. In SM32 CS there is also a service mode function from where the functions can be tested. Mode 2: stand-alone The SM-ARC control panel is configured and operated from the operator panel in the panel front. The roller distance can either be set on the operator panel or through an analog signal from an external system or the distance can be set manual from the operator panel.

PLC setup

There is used a micrologix ML1200 type L24BWA and a PanelView 300 operator panel type 2711-M3A18L1. The PLC and the Operator panel connected to their own NetEni module for Ethernet access. In the stand-alone the NetEni’s are connected with a direct crossed Ethernetconnection, where the setup with SM32 CS communication is connected through an Ethernet switch. The crossed cable connection is standard supply.

Sequence

Starting position: Pellet mill is stopped Roller distance is 100 %

1. The Pellet mill is started The rollers stays at 100 % 2. The Pellet mill is started The rollers are moved towards position 0 % Start of FEX, conditioner and feeder screw is blocked 3. The rollers are at position 0 % Timer T1 (Time for clean run) is started. 4. T1 is expired The rollers are moved towards the set point either from SM32, the analogue input or the operator panel. 5. Roller distance set point is reached (or is within the neutral zone) Start of FEX, conditioner and the feeder screw is released. 6. Production is started The roller stays in the position or moves to the set point if it is changed. 7. The feeder screw is stopped Timer T2 (Time before cleaning at stop) is started. 8. T2 is expired** The rollers are moved towards the position 0% Start of FEX, Conditioner and feeder screw is blocked. 9. The rollers are in position 0 % Timer T1 (Time for cleaning) is started. 10. T1 is expired The rollers are moved towards the set point from SM32, the analog input or the operator panel. 11. The roller distance is at the set point (or is within the neutral zone) Start of FEX, conditioner and feeder screw is released Production can be restarted or the Pellet Mill can be stopped.


If the Pellet Mill is stopped the rollers will move to position 100 % ** If the production is restarted before T2 is expired the rollers will stay at the set point. It is possible to choose if the rollers should NOT move to position 0% for cleaning of the die at start of the Pellet Mill (Cleaning at Start). If it is not chosen, step 1-4 must be ignored. It is also possible to choose if the rollers should NOT move to position 0% at stop of the production (Cleaning at stop). If cleaning at stop is not chosen step 8 and 9 must be ignored. Finally it can be chosen if the rollers should stay at the set point or move to position 100% when the Pellet Mill main motor is stopped.

Start / stop of the Hydraulic pump

The Hydraulic pump is started when pressure is needed to move the rollers. When the rollers are at the right position a timer is started and when the time is expired the pump will be stopped.


Operation from the PanelView 300 Micro

When SM-ARC1 is not connected to SM32 CS (stand alone) all operation will be done from the PanelView 300 Micro operator panel.

Main screen

This is the main screen on the operator panel. Set point: The rollers will be moved to this distance. Can be changed with “Arrow Up” and “Arrow Down”. Scale is in 1/10 mm

Monitoring of the actual roller distance.

Man: Press F1 to change to manual mode. The Distance is adjusted by the Arrows.

Status: Press F2 for status for in and outputs.

Config: Press F4 for configuration.


Manuel operating screen

The Manual mode-operating screen is activated by pressing F1 on the Main screen. In manual mode it is possible to activate the solenoid valves for ”Toward” and ”From” Die by using the Up and Down Arrows on the display. The valves will be activated as long as the Arrow is activated. The access to the Status and the Configuration screens are only available in Automatic mode, done by pressing F1. Manual mode is usually used during test of the system or plugs of the pellet mill.

Status Screen

The Status Screen is accessed by pressing F2 from the Main Screen. On the Status Menu there are 2 options. F1 for digital input Status screen. F2 for digital output Status screen. Use Arrow Up and Down to get back to the Main Screen.


Digital Input Status

All used inputs are shown by a square. A filled square equals the input is on. An empty square equals the input is off. The explanation for each input is mentioned in the section for Input/Output” Press F4 (return) to return to the main status menu.

Digital output Status

All used outputs are shown by a square. A filled square equals the output is on. An empty square equals the output is off. The explanation for each output is mentioned in the section for “Input/Outputs” Press F4 (return) to return to the main status menu.


Configuration from the PanelView

The configuration menu is opened by F4 ”Config” from the Main Menu. In the configuration menu there are the following options: F1: Sequence config. Setup of the Roller adjustment sequence. An example is the possibility to choose a cleaning of the die when the pellet mill is started. F2: Control config. Setup of the regulation and setpoints. F3: Alarm config. Setup of alarms at faults in the system. F4: Analog config. Setup of analog input / output. By pressing F1 from the 4 configuration pages this menu can be accessed.

Name Description Area

Cleaning time The time where the rollers are in position ”0” in the Cleaning sequence.

0-100 sec.

Delay stop clean The time delay from production stop until the cleaning sequence is activated. This time is to secure that the conditioner and the FEX is empty before the cleaning sequence is activated. Has no function if Cleaning at stop sequence is not selected.

0-100 sec.

Clean start It can be chosen if the rollers should move to “0” after start of the pellet mill mainmotor. If cleaning at start is not chosen the roller moves to setpoint after start of pellet mill mainmotor.

0-1

Clean stop It can be chosen if the rollers should move to “0” by stop of production. If cleaning at stop is not chosen the roller stays on setpoint.

0-1

100% at press stop If this function is chosen the roller is moving from the die by stop of the pellet mill motor. If this is not chosen the roller stays on setpoint.

0-1

Regulator configuration

Press F2 to access the Regulator menu. Press F4 to return to the Configuration menu.



Neutral zone If the roller position deviants less than this value from the setpoint there will be no regulation of the roller distance. Neutral zone also counts by 0 % and 100 %

1-10 %

Pump stop delay The hydraulic pump is started when pressure is needed to move the rollers. When the time is expired the pump will be stopped.

0-100 sec.

Alarm configuration

From the configuration menu you press F3 to get acess to configuration of alarms. Press F4 (return) to return to the main status menu.


Position alarm It can be chosen if an alarm is given if the rollers do not reach the set point within the time ”Delay pos. Alarm”

0-1

Delay pos. alarm If the rollers is in neutral zone further time than this time limit an alarm is given and the signal for roller in position is reset. Dosing is stopped.

0-100 sec.

Delay pump alarm If the hydraulic pump dont give a running signal within the timelimit after the start signal is given, an alarm is given and the pump is stopped.

0-100 sec.


Configuration of analog signals.

It is possible to make configuration of the analog signals on SM-ARC1 by pushing F4 from the configuration menu.


Ext. set It is possible to use analog input as set point for roller distance. If you here write 1 the roller will be adjusted after that signal representing 0 - 5,8mm. Set point on the main status menu will no longer have any function.

0-1

Ext. Set 4-20 mA It can be chosen if the external set point signal must be 0-20 mA or 4-20 mA. If you write 0 the signal must be 0-20 mA and 4-20 mA if you write 1.

0-1

Ana. Out 0 4-20 mA It can be chosen if the output for roller distance in percent must be 0-20 or 4-20 mA. 0 = 0-20 mA 1 = 4-20 mA

0-1

Ana. Out 1 4-20 mA It can be chosen if the output for roller distance in mm must be 0-20 or 4-20 mA. 0 = 0-20 mA 1 = 4-20 mA

0-1

The menu for setting up analog signals is also used to calibrate the distance sensor zero and max signal. In cases where the distance sensor zero point and maximum is not 4 and 20 mA it will be nessesary to make a calibration. The calibration is made by pushing F1. The rolls is now automatically running as far as possible from die and the signal from the distance sensor is saved as maximum calibration. After this the rolls are running as close to the die as possible and the signal from the distance sensor is saved as minimum calibration.

Calibration status

Start calibration

Insert standard values


Under calibration the following text is shown ”Calibrating…” in the status field. If the calibration is succeed the following text is shown ”Success” in the status field in about 5 sec. If the calibration is failured the following text is shown ”Cal. Failed” in the status field. The return to the preinstalled calibration you must push F2 “DEFAULT”. This function inserts 4 mA as minimum calibration and 20 mA as maxisimum. F2 can also be used for interrupt the calibrations. After the F2 is pushed the folowing text is shown Defauld installed.

Calibration can not be done if the production is started.
