power reduction is not sufficient, the low-power measurement impulses are suspended to determine the current
ACTUAL temperature. This measurement pause can last up to 10 periods in the standard setting. During this
measurement pause, the controller cannot respond to a change in the ACTUAL temperature. The status bit “Meas-
urement interruption active” (
section 9.3.10 "Measurement interruption (MU)" on page 36) is active at this time
(MU bit = 1).
In certain applications it may be useful to shorten this maximum measurement pause, e. g. if the higher ACTUAL
temperature values are measurement errors. For this case, the maximum measurement pause can be shortened
with the CANopen object 0x4015.
The maximum measurement pause cannot be set in the ROPEX CAN protocol.

The flawless functioning of the RESISTRON
®
Temperature Controller RES-5009 is guaranteed for the tolerance
range of the line voltage and 24 VDC supply voltage specified in section 15 "Technical data" on page 91.
If the 24 VDC supply voltage falls below the permitted tolerance range, the controller switches to a standby mode.
Welding processes and measuring impulses are no longer carried out. If the input voltage is within the specified
tolerance range again, operation will be continued. As an indication of the standby state, 0…3 °C (i. e. approx.
0 V) is output at the analogue output. In addition, the SA bit is set in the controller status.
CAUTION
A measurement pause that is set too short can lead to an increased temperature if the system
is incorrectly dimensioned (secondary voltage of the pulse transformer too large) or if the
sealing temperatures are low.
WARNING
The flawless functioning of the RESISTRON
®
Temperature Controller RES-5009 is guaranteed
only within the specified tolerance range of the input voltage. An external voltage monitoring
device must be used to avoid faulty welding if the line voltage or the 24 VDC supply voltage is
too low.
