Installation
Hazardous voltage.
Voltages above 60 VDC or 30 VAC and can cause severe injuries.
The RELAY connection may be used for switching voltages of max. 60
VDC or 30 VAC only. These voltages must meet the requirements of a
ground protective extra low voltage (SELV).
1
Connect the peripheral components with the RELAY connection. Use a
shielded connection cable.

CONTROL
The CONTROL connection (Fig. 3-4,
18, item D) contains the following sig-
nal pins:
Analog outputs for the signals of the individual channels
Recorder output. This is a programmable analog output which can be as-
signed to one of the three channels.
HV-EMI. Used to switch the high-vacuum circuit of the PTR 225 transmitter
on and off. The signal levels are: On = +24 V. Off = 0 V. See Reference [3].
