Error Number Meaning Error cause – and removal
E003 over-current error of the output Short circuit at the output, Peltier module defect
> check wiring / correction
> check Peltier module / replace
> eventually contact factory
E004 Controller overheated Inside temperature of the controller too high
Ambient temperature too high, Instrument exposed
directly to the sun, output overloaded
> avoid excessive external warming
> eliminate overloading
> reduce eventually PWM-Limit

3.10 Communication
3.10.1 Overview
The below mentioned information will be required for the implementation of own Control-Software. Otherwise
you can ignore them.
3.10.2 Block Format
It has been implemented a simple ASCII-Protocol. To simplify the use of the serial communication the program
“TCCOM.EXE” has been developed. It is included with the RS232 option.
It is also possible to use a simple Terminal-Program even it’s less comfortable.

Command (only Master) <address> _ <command> _ <parameter> _ <value>§
Acknowledge (only Slave) . / ? / #
Response (only Slave) <value> §
The several components are defined as following:
address A..Z (actually only A)
command a..z (actually only d, r, u, w)
parameter 0..65535
(no leading zeros, negative figures will be transferred as positive figures, and
then accordingly interpreted “typecast”)
value 0..65535
(no leading zeros, negative figures will be transferred as positive figures, and
then accordingly interpreted “typecast”)
