Product Description

Four-channel multiplexed system with manual and automatic operation modes. This system is extremely dirt resistant and specially tailored to operate in car washes.

Menu-driven setup allows individual parameter settings for each channel:

Automatic mode with 4 levels, manual mode with 2 levels
Manual gain setting
Light/dark switching
Switching delay (on/off) 0-60 s

Sensor error monitoring shows error messages on the LCD display during normal operation. Info screens for each channel indicate the current settings and performance. Detailed performance and error information are indicated in diagnostic mode.

The Master/Slave operation makes it possible to synchronize several amplifiers of the series ISM-4xxx and ISM-8xxx. This function is essential due to strong reflections if more than one amplifier is used in a car wash.

Test input for functional test by external test equipment. The PC-Interface allows the user to connect the ISM device to a computer and use the WinISM software to display device functions and set all device parameters.

LED indicators for output signal and sensor error per each channel. Alarm indicator, alarm and error output. Electronic output stage (PhotoMOS). Plug connector version for easy installation.
