20 Electrical characteristics
The following subsections contain useful information for machine builders and debuggers.
20.1 MAF light guard interface
The 24V is shared with the 24V [ZA9-ZC9] in the EUROMAP 67 cable. However, the input
signals to the controller box are low current types and therefore most of the current is available.
It is recommended to keep the load under 1.2A. The 24V current and voltage is shown on the
EUROMAP 67 I/O tab.
The two MAF signals must connect to potential free switch contacts. The MAF signals are
0V/0mA when the "Moulding Area Free (Software)" bit is off.

20.2 Emergency stop, safety devices and MAF signals
The signals signalling emergency stop and MAF to the IMM are controlled by force guided
safety relays conforming to EN 50205. The switch contacts are galvanically isolated from all
other signals and conforms to IEC 60664-1 and EN 60664-1, pollution degree 2, overvoltage
category III.
The signals signalling emergency stop and safeguard stop (safety devices) to the robot are con-
nected to the potential of the controller box.
Version 3.11
NOTE:
The "MAF light guard interface" signals are not galvanically iso-
lated from the shield of the controller box.
