MCS Functionality Control behaviour Automatic determination of the control parameters P I D During the heating nozzles and manifolds are classified (automatic detection between sluggish and fast control loops) and the PID control parameters determined. Suppression of overshoots At aggressive control circuits, overshooting can be reduced when heating up. Pulse mode / phase-fired control Pulse mode and phase-fired control are two different ways of controlling heating. Thus the controller reaches a high control precision, even in sensitive processes. (devices starting at 20 zones)

MCS Functionality Heating Gentle heating Gentle heating by reducing the output rate in dependance of the temperature. Group heating Zones are heated up so that they must only have a specific temperature difference from each other. Sequential heating / cooling Zones can be heated and cooled sequentially. Ramp The ramp function enables a slow and uniform heating / cooling of zones by specifying a rise / cooling curve.

MCS Functionality Zone monitoring Temperature monitoring Supervision of the zones to under- or overtemperature. Sensor monitoring The behavior at sensor break can be determined. Material leakage monitoring Irregularities in heating e.g. material leakage can be detected Leakage current monitoring Records leakage currents outside of a specified tolerance limit. Heating current monitoring The heating currents are measured for each zone. A deviation from the nominal values ​​can be monitored and displayed. Triac monitoring Device monitoring with LED indication with a defective triac.

MCS Functionality Special functions BOOST Raising the temperature of groups or individual zones for a set period of time. STANDBY Lowering of the temperature to a specific value. Diagnosis Detecting wiring faults as well as heating and sensor defects. Programs Recipes with setpoints, parameters and operation mode can be stored as programs and also be activated via the digital input.

Sensor Monitoring Zone parameter System parameter 10 16 AP Description Alternative Zone 16 Nominal output rate AP Auto Power Description Behaviour at sensor break with the parameter AP Auto Power AP=0 Output rate = 0% The zone remains in Control Mode and must be switched manually to manual mode. AP=1 Output rate = Medium Output rate The zone is automatically switched to manual mode. The output rate will be queried. The medium output rate can be assumed or a new value must be entered manually. AP=2 As AP=1 but without confirmation query AP=3 Output rate = Nominal output rate The zone with sensor break automatically switches to manual mode and applies the nominal output rate to be specified in parameter 16. AP=4 Output rate = Alternative zone Parameter 10 specifies the zone that delivers the output rate at sensor break. 16 Nominal output rate 10 Alternative Zone

Output rate monitoring Zone parameter 17 Average output rate 18 Output rate monitoring average 19 Output rate monitoring tolerance Description The output rate monitoring serves to recognize irregularities in heating, e.g. at a leaking nozzle from which liquid plastic may leak (plug formation). When the controller is in steady state and the process is stable the controller generates internally an average output level. This average output level can be monitored for deviations (plus / minus).

Output rate monitoring Zone parameter 17 Average output rate 18 Output rate monitoring average 19 Output rate monitoring tolerance Method Step 1 Heating ... Let the system work at the setpoint for approximately 10 min. The determined value is shown in the zone parameter No. 17. Step 2 Enter this value as a kind of monitoring at the "output level setpoint" in zone parameter No. 18. Step 3 Enter in zone Parameter No. 19 the desired tolerance as a % value. Example 50% is the output level to be monitored, desired alarm at 45% and 55%, means the value "5" is to be entered in parameter No. 19.

Gentle heating 1 1 Zone parameter Soft start Description Soft start = Gentle heating All zones are gently heated separately of each other to max. 100 °C, independently of a higher target temperature set. Up to a temperature of 50 °C, each zone is heated with a max. output rate of 50%. From 50 – 100 °C, the output rate is determined based on the present temperature, i.e. from 60 °C onwards the output rate is 60%, etc. After 100 °C are reached, the soft-start is complete and the zone can heat up at full output. Soft start is already pre-set ex works. Parameter Zone parameter Einstellungen   11 Soft start 0: No soft start 1: This zone with soft start Standard value: 1

Group heating Zone parameter System parameter 12 Ct Description Group (combined) heating Ct Max temperature difference of the group Description Slow heating with consideration of the slowest zone This is to prevent the complete tool, manifold and nozzles from being heated up with thermal dysbalances. All zones are heated up so that they must only have a specific temperature difference from each other (system parameter Ct = Max temperature difference of the group). The slowest zone works at the maximum output rate and the other zones will be limited in their output rate so that they must only advance by the set temperature difference. The parameter 12 defines the assignment of a zone to the "Group".

Group heating … Cont. Parameter Zone parameter Settings 12   12 Group (combined) heating 0: This zone without group 1..8: Zone/group in group heating. Higher values are heated up first. System parameter Ct Max temperature difference of the group Can be set from 1° … 100° Standard value: 25° Example Zones 1 to 6 are to be heated together. The temperature difference during this heating process is to be 20 °C at most. Zones 7 and 8 are not to be part of the heating group. Settings: Zone 1 to zone 6: Parameter 12 = 1 Zone 7 and zone 8: Parameter 12 = 0 System parameter Ct = 20

Sequential heating / cooling Zone parameter System parameter 12 Group (combined) heating Ct Max temperature difference of the group COL Cooling Limit Description Zones are heated or cooled ina sequentiel order The heating process starts with the zones/groups that have the highest set value at the parameter 12 = group heating (max. 8). This is followed by the zones with the lower values. A group or zone will start its heating phase only when the preceding group or zone has reached 10 °C below the setpoint. If no zones or groups are summarized for parameter composite heating, all zones will start without delay without the function sequential heating. Sequential cooling works according to the same rules as heating, but in the reverse order.

Sequential heating / cooling Example Zone 1 is to be heated first then zones 2,3,4 are heated together. Only then should zone 5 be heated. Settings of the parameter 12 "Group heating" Parameter 12, Zone 1 = 3 Parameter 12, Zone 2,3,4, = 2 Parameter 12, Zone 5 =1
