Page 4: Overview
Overview SensorShield-1600™ follows the same self-cleaning principles as the ToughEye-1700™ line of cameras, providing industry-leading, zero maintenance, self-cleaning operation for rear-mounted optical sensors and cameras, suitable for any industrial application where a clear view is critical to the success of the operation.
Page 5: Important Safety Instructions
In such a circumstance, do not attempt to handle conductors before removing power. 5. The SensorShield-1600™ viewing region is made with hardened glass. The user should take necessary precautions when handling the system. If excessive, direct force is induced, the glass may break, causing system failure and potential injury to the user.
Page 6: Caution
3. Do not attempt to disassemble SensorShield-1600™ in order to access internal components. Consult ExcelSense for technical support as required. 4. Never face the SensorShield-1600™ directly towards the sun or any bright or reflective light, which may cause damage to any internal sensors mounted behind it, such as cameras.

Typical Installations Important Note: As per rule 2-024(2) of the Canadian Electrical Code Part I, SensorShield-1600 does not require approval in order to be installed. However, it must be connected to a Class 2 output, as permitted by the Canadian Electrical Code Part I. (See rule 16-222 and relevant appendices).
Page 10 a. The recommended wire gauge for the screwless terminal connections (+V, GND, TRIG) is 18-22 AWG. b. The recommended wire finishing method is ferrule application. Wire may be tinned, where ferrule application is not available. c. For long cable runs, voltage loss must be taken into account in order to ensure the voltage at the device does not fall below its minimum voltage (see Specification table) 2.

Triggering the SensorShield-1600™ The SensorShield-1600™ performs cleaning cycles in response to a trigger event. The triggering event method is an important consideration at the time of specifying your system topology. The decision is based on many factors, including availability of a digital switch, remote triggering requirements, and the general nature of the application.
Page 15: Manual Trigger Using External Button
0V or Open The recommended minimum hold time at a logic level state, t , is 0.5 seconds. Using this control, the SensorShield-1600 can be configured for the use case seen below. Manual Trigger using External Button In manual trigger applications where on-demand vision is required, the trigger can be simply wired to a normally-open momentary button as shown below.

Page 22: Data Memory Mapping
Data Memory Mapping The following table details all coils and registers available on the Modbus interface. Note: Data is considered non-volatile if its value is stored onto local non-volatile memory, unaffected by loss of system power. Conversely, data is considered volatile if its value is lost in the event of a power cycle.

Page 30: Lscr - Lifetime Stall Count Register
The base data type of the cycle count variable is a 4-byte unsigned long (32 data bits). The value of the cycle count can be determined by performing the following mathematical operations: cycleCount_32bits = (val << 16) + val LCCH LCCL Note: Due to system memory optimizations, the system’s internal memory stores cycle counts to the nearest 10 cycles (i.e.

However, the error register, EREG, is showing that there are no errors currently detected by the system iii. Also, enough time has elapsed since the last cleaning cycle (based on the CTOR register) so the system should not be in a cycle timeout state. b.
Page 36 The Last Cycle Status Coil can be used as an indication of the success of the previous cleaning cycle, based on a closed-loop cleaning system. If the last cycle was successful, this coil will be asserted high by the system and vice-versa if an error was detected during the cycle, which may have resulted in premature cycle completion.
