RES-5008
Page 45
If the 24 VDC supply voltage falls below the permitted tolerance range, the RESISTRON
®
Temperature Controller
RES-5008 switches to a standby mode. Sealing processes and measuring impulses are no longer carried out.
This is shown by a special message on the display.
When the input voltage is found again within the specified tolerance range, the basic menu is displayed again and
the operation continues.
0 °C (i.e. 0 V) is output at the analogue output, as an indication of standby status. The alarm relay is not active.

Booster connection
Normally, the RESISTRON
®
Temperature Controller RES-5008 has a connection for an external switching ampli-
fier (booster). This connection of an external switching amplifier (at the terminals 15+7) is required at high primary
currents (constant current > 5 A, impulse current > 25 A). The switching amplifier must be connected in accord-
ance with section 7.7 "Circuit diagram with booster connection" on page 19.
CAUTION
In order to avoid the EMC interference, the connection cable to the external switching amplifier
may not exceed a length of 1 m and has to be twisted.
9.22
USB-interface for visualisation software ROPEXvisual
®
A USB interface (type micro-USB) is available for system diagnosis and process visualisation. A data connection
can be built up with the ROPEX visualisation software ROPEXvisual
®
over this USB interface.
WARNING
The proper function of the RESISTRON
®
Temperature Controller RES-5008 is guaranteed only
within the specified tolerance range of the input voltage. An external voltage monitoring device
must be used to avoid faulty seals, if the mains or the 24 VDC supply voltage is too low.
