S1 SEN / PR / IMM / 001 Plant Room Sensors Immersion Temperature Sensor IP65 rated Measures the temperature of liquids in pipework and vessels. Direct mounting into a brass or stainless steel pocket (separately available as an accessory). Dimensions: 57mm x 90mm diameter IP rated 67 Ambient: -10 to 60 Connection: 2 way terminal block, Houses sensor Dimensions: 150mm x 6mm diameter Material: Brass If the sensor is to be mounted outside, it is recommended that the unit be mounted with the cable entry at the bottom. In addition, if the cable is fed from above the sensor we also recommend that a rain loop is placed in the cable before entry into the sensor. Remove the front cover by twisting the lid and separating from the main body to make the electrical connections. Fix the sensor in to the pocket and secure with the grub screw provided with the pocket. Feed the cable through the waterproof gland and terminate the cores at the terminal block. Leave some slack inside the unit, tighten the cable gland onto the cable to ensure watertightness. Replace the lid after the electrical connections have been made. SEN / PR / CLP / 001 Measures pipe surface temperature. Includes steel band strap for clamping onto pipes (may require longer strap for larger vessels). Clamp-On Temperature Sensor IP65 Dimensions: 57mm x 90mm diameter IP rated 67 Ambient: -10 to 60 Connection: 2 way terminal block, Houses sensor Material: Brass Cable: 1.5m of PTFE 2 core screened cable If the sensor is to be mounted outside, it is recommended that the unit be mounted with the two cable entries at the sides. In addition, if the cables are fed from above the IP65 housing we also recommend that a rain loop is placed in the cable before entry into the sensor. Remove the front cover by twisting the lid and separating from the main body. Using the base of the housing as a template mark the hole centres. Drill two pilot holes at 85mm centres in the surface on which the sensor is to be mounted, and fix the sensor with appropriate screws. The housing is designed to make it easy for an electric screwdriver to be used if desired. Feed the cables through the waterproof glands and terminate the cores at the terminal blocks. Leaving some slack inside the units, tighten the cable glands onto the cables to ensure watertightness. Replace the lid after the electrical connections have been made. smartkontrols Data Sheet S1 Part No LIT / DAT / SEN / 001 Iss 1 Jan 2002 Page1 2 of 8
Plant Room Sensors S1 SEN / PR / OAT / 001 Measures outside air temperature. Sensing is contained within 10mm diameter brass cap, located externally in the shadow of the lid to avoid solar gain in most applications. Outside Air Temperature Sensor IP65 Dimensions: 57mm x 90mm diameter IP rated 67 Ambient: -10 to 60 10mm diameter brass cap houses sensor Connection: 2 way terminal block, Cable: 1.5m of PTFE 2 core screened cable Outside air sensors should always be situated in a sheltered position on a north facing wall. Avoid mounting the sensor in direct sunlight. It is recommended that the unit be mounted with the cable entry at the bottom. In addition, if the cable is fed from above the sensor we also recommend that a rain loop is placed in the cable before entry into the sensor. Remove the front cover by twisting the lid and separating from the main body. Using the base of the housing as a template mark the hole centres. Drill two pilot holes at 85mm centres in the surface on which the sensor is to be mounted, and fix the sensor with appropriate screws.

Leaving some slack inside the units, tighten the cable gland onto the cable to ensure watertightness. Replace the lid after the electrical connections have been made. SEN / PR / DCT / 001 Duct Temperature Sensor Measures air temperature in ducts. Sensing is contained within 150mm long brass probe with holes to allow air to flow directly over the. A neoprene gasket is supplied to ensure a good seal onto the duct. Dimensions: 57mm x 90mm diameter IP rated 67 Ambient: -10 to 80 Connection: 2 way terminal block, Houses sensor Dimensions: 150mm x 6mm diameter Material: Brass If the sensor enclosure is to be mounted outside, it is recommended that the unit be mounted with the cable entry at the bottom. In addition, if the cable is fed from above the sensor we also recommend that a rain loop is placed in the cable before entry into the sensor. Remove the front cover by twisting the lid and separating from the main body. Using the base of the housing as a template mark the hole centres. Drill two pilot holes at 85mm centres in the surface on which the sensor is to be mounted. Apply the gasket provided to the base of the housing. Align the holes in the probe so that they point into the airflow, not at right-angles to it. Press onto the side of the ductwork to form a seal between the sensor and the duct. Fix the sensor with appropriate screws. The housing is designed to make it easy for an electric screwdriver to be used if desired. Feed the cable through the waterproof gland and terminate the cores at the terminal block. Leaving some slack inside the units, tighten the cable gland onto the cable to ensure watertightness. Replace the lid after the electrical connections have been made. smartkontrols Data Sheet S1 Part No LIT / DAT / SEN / 001 Iss 1 Jan 2002 Page1 3 of 8

Sensor Installation S1 Wiring Guidelines Sensor cabling should be to the same specification as per the SeaChange Network - Unscreened, Twisted pair Belden 8205. Use twisted pair, unscreened cable for all sensor wiring (and input wiring - e.g. from contactor auxiliaries, flow switches etc). Use this cable for the entire run from the SeaChange input terminals to the sensor. Recommended maximum cable length 100m. Do not use single conductors, even for short runs in the panel; an electrical panel is often a noisy electrical environment. If already installed, Screened twisted pair cables can sometimes be re-used for sensors without detriment provided the screen is continuous and properly earthed at one point only. Do not use screened cables on new installations. New installations should always use the correct Unscreened, Twisted pair cable. Sensors should be of the insulated type and not earthed. There is no particular requirement to segregate from Mains wiring, but prudent installers will always avoid long, parallel runs. Inputs All inputs to SeaChange modules are Non-Isolated; this means that you must not connect inputs from different controllers together, or connect inputs to 0V or earth, or any other potential.
