5 General description
The mains operated display unit RM-32 is designed for continuous monitoring of lamps
mainly UV lamps. In addition to lamp monitoring, absorption, transmission and reflection
measurements can also be carried out.
The display is digital (3 1/2 digits) in W/m2. Two light-emitting diodes (SP1, SP2) indi-
cate the status in relation to two preselectable thresholds. Two relays with switching
contacts are activated simultaneously. The relay functions can be triggered with a time
delay.
The device is programmable and can control numerous parameters of the measure-
ment process with its integrated measurement routines.
Optional USB, RS-232 or RS-485 interface is available.
Connect the supplied sensor to input 2 and 4. Only use the sensor type for which you
ordered the device. Connecting a different sensor type can lead to malfunctions. Follow
the instructions for the sensor carefully.

Data transmission of the measured values of the SPE670 via serial interface.
Routine 25: Activate/deactivate the serial interface
Routine 27: Setting the baud rate of the serial interface
Routine 34: Transmission cycles for the serial interface
Jumper JP4 can be used to bypass the enable/disable by routine 25, the interface is
then always active. The cycle setting of routine 34 remains valid. Thus, the interface
can still be deactivated by a transmission cycle of 0.
The individual characters are transmitted in ASCII code. The sign of the measured
value is sent as a minus for negative values, otherwise as a space. The transmission
starts with the first character of the day and ends with LF (line feed - 10d, 0Ah) and
CR (carriage return - 13d, 0Dh) to start a new line at a connected printer or screen.

Routine 34 Transmission cycles for the serial interface
At intervals of the set transmission cycles, the measured value is sent with date and
time via the serial interface. The set number is evaluated in minutes and is the time
interval between two transmission processes. Please note that the serial interface is
generally enabled for transmission with routine 25.
must be. Setting range: 0-255
0 = Timer stop (no transmission)
1 = 1 minute
2 = 2 minutes
...
255 = 255 minutes (4h 15min)
The number of transmission cycles also affects the transmission of the measured val-
ues when jumper JP4 is closed. If set to 0, no transmission takes place.
Routine 35: Dimension of the measured value
The dimension is the physical size of the displayed measured value (e.g. m=milli,
μ=micro, p=Piko.... °=degree) The dimension does not appear in the display of the
SPE670 but only in its printout. The dimension is entered as ASCII code decimal. For
special characters (codes 128-256) the international code table from IBM (code page
437) is used.
Examples:
° = 248, m = 109, n = 110, p = 112
k = 107, M = 77, G = 71
Routine 36: Naming the measured value
The designation is the physical type of the displayed measured value (e.g. V=Volt,
A=Ampere, ....C=Celsius) The designation does not appear in the display of the
SPE670 but only in its printout. The designation is entered as ASCII code decimal.
For special characters (codes 128-256) the international code table from IBM (code
page 437) is used. Examples:
A = 65, C = 67, V = 86, Û = 234 (Ohm)

11 Sub-D RS232 adapter 15
Routine 37: User-defined character of the measured value
The user-defined character extends the display to three characters, which allows in-
formation such as "Bar". The character does not appear in the display of the SPE670
but only in its printout. The character is entered as ASCII code decimal. For special
characters (codes 128-256) the international code table from IBM (code page 437) is
used.
Examples:
B - 66 in routine 35
a - 97 in routine 36
r - 114 in routine 37
m - 109 in routine 35
A - 65 in routine 36
- 32 in routine 37

Jumper and start display
Jumper JP4: If jumper JP4 is plugged in, measured values are transmitted via the se-
rial interface in the set transmission cycle. Even if the interface is deactivated by rou-
tine 25. Routine 34 can be used to set the transmission cycles or to suppress trans-
mission.

13 Radiation protection
UV radiation is harmful to humans, therefore observe the protective regulations when
working. Furthermore, UVC radiation in particular has a material-destroying effect. It is
therefore advisable not to expose the sensors to too much radiation. If possible, avoid -
exceeding the measuring range in the least sensitive setting and use an aperture in
good time.
If the thermal load caused by the radiators is too high, it may be useful to place a shield-
ing hood over the sensors, which only exposes the receiver surface. This can significa-
ntly reduce the heating of the sensors.
