System
Function description
The TMS is only in function, when a MAG CT version is connected. The
heater will be activated when the mains is switched on. The TMS controls
the heating and water cooling to maintain the pump at the specified setpo-
int temperature.
In order to maintain an almost homogeneous temperature distribution in the
pump the system is equipped with several temperature sensors. The mea-
sured values of these sensors are used to determine two temperatures for
the TMS: T
TMS
and T
A
. Both temperatures are used to switch on and off the
heater and the cooling water valve.

Settings
The temperature (TMS) setpoint can be programmed via the front panel
keys at every time.
Principally the factory presetting will be used. The setting is saved in the
pump’s memory chip. Before changing any setpoint value request Leybold!
For the setting refer to 3.10.6 Operating menu, Set TMS.
Heat up
The setpoint temperature will be reached within 30 to 60 minutes depen-
ding on cooling and environmental conditions. For temperature sensitive
applications observe the cooling water specifications (refer to Section 1.6
and 2.5).
In order to guarantee correct temperature setting of the pump it is
required to provide the cooling water within the envelope descri-
bed in Section 2.5.
