The power supply is physically isolated between power supply input and system power
supply output. This also applies to the analogue and signal outputs which are physically
isolated from each other as well as from the other electronics.
There is no electrical isolation between monitoring head and central electronic unit.
Connection of the monitoring heads is by means of precut cable links.
Cables and user interface connections are shown in para. 2.3.2 and circuit diagram 2.3.2.1/ 2.3.2.2.
System configuration and parameter setting are by means of the keyboard if default values
need to be changed. (paras. 5 and 6)
This mainly applies to monitoring head selection, signal outputs (switch point setting) and
analogue outputs (zero point setting and scaling).
1.2.1 User interfaces
Signal outputs: 1. R2 - Relays outputs (2 limit values)
(optional) Two-channel physical isolation, relay change over contact
The channels may be assigned in menu “CONFIGURATION”, either
individually or in pairs, to the physical quantities of temperature or
flow. The switch on and off values can be set as desired in menu
“PARAMETERS” (yet within the measuring range) for each contact.
Please see para. 8.4.1 for electrical connection.
2. T4 - Transistor outputs (2 setpoints + 2 status outputs or 2 setpoints +
1 status output + frequency output)
Four-channel physical isolation, transistor output - collector/emitter
(NPN) freely connectable
Channel 1: common error signal
Channel 2: busy signal or frequency output
Channels 3 and 4: Both channels may be assigned individually or in
pairs to the physical quantities of temperature or flow. The switch on
or off values of each transistor output can be set as desired.
Please see para. 8.4.2 for electrical connection.
Analogue outputs: Two-channel physical isolation, current or voltage output
(optional) Please see the ordering number to find out whether it is a current or
voltage output.
Output quantities: 0/1 - 5 V FS (option V1)
0/2 - 10 V FS (option V2)
0/4 - 20 mA FS (option C1)
These FS (full scale) output quantities apply to both channels (flow and
temperature) as standard.
20% zero elevation and FS value can be programmed. (See para. 5.11)
Shield connections are ungrounded.
The shields of the signal cables should be applied on one side only.
