Mounting: on a wall or directly on the pipe using
support brackets, SB-100 / SB-101 /
SB-110
T sensor
Type: 3-wire Pt 100 according to IEC Class B
Sensor head: 50 mm x ∅ 5 mm
Cable length: 3 m*
Cable diameter: 4 mm
Cable exposure T: –40°C to +150°C
(+215°C intermittent 1000h)
* The sensor cable can be extended with a 3-core shielded cable of 20 Ω
max� per conductor (e�g� up to 150 m with a 3x1�5 mm² cable)�
The shield shall be earthed on the controller side only�
FUNCTIONAL DESCRIPTION
During normal operation, the display alternates between the measured
temperature and the set point temperature�
When the measured pipe temperature exceeds the programmed setpoint
value plus hysteresis, the switching contact opens and the heating cable
is switched off�
When the measured pipe temperature falls below the setpoint value
minus hysteresis, the switching contact closes� A LED in the display
indicates that the heating cable is switched on�
In the event of an error, the alarm relay switches and an error code shows
on the display� It is possible to program the status of the heating cable (on
or off) in case of a sensor error�
The unit is fitted with a battery so that programming can be done on
the bench prior to mounting in the working location (see Operational
description, page 11)�
DISPLAY
RAYSTAT-CONTROL-10 has a digital display� The three left hand digits 9a
are the value display and the right hand digit 9b is the status display�
There are 4 different display modes possible:
1� In the normal operation mode (no error condition), the measured
temperature or the set point temperature value are displayed in the
value display (alternating)�
