Sef 100 Master Alarm Listing for the following models
Series 8 AT
Mega T
Mega TE
Mega HCS
All alarms are designated by level of priority, exceptions and then the alarm code.
For example: 03 1 01.1 "Alarm Description"
03 = the first byte is the level of alarm (Refer to First Byte descriptions)
1 = Resulting condition of the alarm (Refer to conditional chart)
01.1 = Describes the alarm
First Byte Descriptions
All alarms are designated by level of priority
Level 0 = Video message only
Level 1 = Immediately stop the cycle and shuts down the pump motors
Level 2 = Immediately stops the cycle but pump motor remained engerized
Level 3 = Stops the cycle at the end
Level 4 = Stops all automatic operation at the end if the alarm is not reset within
60 seconds.
Level 1 = Immediately stop the cycle and the pump motors in all modes in additonal
to shut off the heater function. The visual and audible alarm will sound.
To reset: Change the mode of operation and then acknowledgement of the alarm is required.
Level 2 = Immediately stop cycle and if the selected the pump motors after 60 seconds
plus shutting down the heater operation. A constant video alarm is visable. Visual and audible alarm only in automatic
and semiautomatic modes
These alarm outputs can be reset by changing the mode of operation.
The video message can be eliminated by changing the automatic modes of operation
to either Manual or Maintenance mode.
Level 3 = Alarm and all movements stop at the end of the cycle if the option is selected.
Reset procedure is similiar to Level 2 corrections
Level 4 = Constant video alarm. Visual and audible alarms only is Automatic
and Semi. If the alarm condition is not corrected in 60 seconds then the all movements are stopped. Correction
methods are similar to Level 2.
Conditional effect description Chart
0 = No effect
1 = By Pass Screw movements = in automatic and semi modes the machine sequence skips
all screw functions.
2 = Siren alarm in Manual and Maintenance, siren is activated in manual and maintenance
modes.
4 = Stop Heater Operation = The Heater Master Contactor is deengerizes by alarm.
8 = Stop motors at the end of of cycle. When the cycle is completed then the
pump motors shutoff.
16 = Motor Inactive. The pump motors will not start in all modes.
32 = Mode of operation is inactive. Maintenance mode is only active.
Other modes cannot be selected.
64 = Start Cycle cannot be initiated. The machine will not acknowledge the
cycle start input.
128 = Level 1 + Warning. A visual message will appear on the screen when the
pump motor button is pressed.
Alarms 03 (2 and 8) 12.1 = Lubrication oil network: Oil level is low or empty.
Corrections:
1. Check the oil level in the tank
2. Check the operation of the level switch.
3. Check the plug on the tank.
Reset: Fix the problem and then clear the alarm by changing mode of operation between
the automatics mode and manual or maintenance
Alarm 03 (2 and 8) 13.1 = Lubrication oil network: pressure insufficient
This alarm is caused by a the lubrication pressure switch contacts not closing after
the lub pump has been cycled.
Possible causes:
1. Broken tubing, piping or broken metering unit.
2. Lubrication pump is damaged
3. low lubrication level
4. No power to the lubrication sensor
Possible solutions
1. Verify that all lubrication circuitry components are secure and free of damage.
2. Verify that the lubrication pump is pump and the system pressure is at 70 bars.
02 0 19.1 = Mold Opening Not Completed
Alarm desciption: The clamp has open to its setpoint.
Possible causes:
1. Mechanical problems
2. Insufficient clamp opening pressure
3. EV7 needs to be recalibrated
4. Slow down or braking parameter needs adjustment
5. Cylinder seals are damaged
6. Air in the system
7. Clamp transducer issues
Possible solutions:
1. Bleed air from the system
2. Recalibrate the EV7 solenoid
3. Verify that the clamp transducer signal is not being affected by noises.
Check the cabling and the grounding of the shield. If replacing the cable be sure to use twisted pair cabling (12 twists
per inch) that's made for high flexing applications.
02 0 19.2 = Premovement Not Completed
Alarm desciption: This alarm is caused by the premovement being selected by there's
movement.
Solution: Chances are the premovement function is on by there's no velocity
Go the Clamp screen and either set the premovement position to maximum clamp opening
stroke or enter a velocity if you're going to use it.
