Power setting (MM DN750…1850, optional)
The power setting is chosen via either of the following options. A DN can only be equipped
with one.
•
Selector switch on control panel
•
D-SUB9 power setting interface
The power setting allows selecting between 3 configured power settings. The following
configuration are default settings. A customer-specific configuration is possible.
Setting
Default configuration
1
50% field strength
2
75% field strength
3
100% field strength

6.6.1 Power setting via selector switch
Select power setting via selector switch on control panel.
6.6.2 D-SUB9 power setting interface
Interface signals maximal current load 100mA.
D-Sub15 PIN14/15: 0...10 VDC Output maximal current load 1mA.
Do not connect D-Sub interface to a PC verbinden. PC and power module may be
damaged.
Power settings can be controlled via
D-SUB9 power setting interface.
The interface is
electrically isolated and requires external power supply.
6.6.3 Configuration D-Sub9 connector
Find the configuration and voltage range of the D-Sub9 connector in the appendix.
To select a power setting supply +24VDC to PIN1, PIN2 or PIN3. If no PIN is supplied the
maximal field strength is selected.
PIN1/2/3 select setting 1/2/3
Do not 24VDC simultaneously to more than 1 PIN.
Do not change signal on PIN1/2/3 during demagnetization pulse.
24VDC on PIN1/2/3 during the entire length of the demagnatization pulse.
6.7 Continuous demagnetization
Depending on the coil module the machine can be configured for continuous demagnetization.
The configuration is set up by Maurer Magnetic before delivery.
Continuous operation is controlled via
D-Sub15 Control Interface
. As long as +24VDC is
supplied to PIN2 (
Start
) the demagnetization is active. When PIN2 drops to 0VDC the
alternating field declines analogue to the pulse demagnetization.
