3 Installation (continued) Mounting (continued) This symbol indicates that the HMM/HC models are fully encapsulated for reliable protection against condensation on the integrator board. Protection class: IP68. The sensors may either be mounted in ball valve or adapter, or in a pocket: Either mount temperature sensor in ball valve or adapter Fixing Kit O -ring Note that the sensor fixing kit (HMAC/SENSORFIXKIT) is not required if mounting the sensor in a pocket. The fixing kit is only required if mounting in a ball valve or adapter. split screw mounting pin One fixing kit is provided with DN15/20 meters (only one is needed for these as the other sensor is already fitted in the body of the unit). Two fixing kits will be required to be purchased separately for DN25/40 meters if using ball valves or adapters. A B C D 1. For ball valve only, close the ball valve and unscrew the plug screw from the ball valve. 2. For ball valve or adaptor place an O-ring on the mounting pin (A). The second O-ring is spare.. Insert the O-ring into the hole of the ball valve or adapter with the mounting pin using turning movements (B). 4. Position the O-ring in its final position using the other end of the mounting pin (C). 5. Place the two halves of the plastic screw around the temperature sensor. Press the two halves together so that the two studs on one half of the plastic screw fit into the holes on the other half (D). 6. Insert the temperature sensor with the plastic screw into the ball valve or adaptor and tighten the plastic screw by hand. 7. Check for leaks. Or mount temperature sensor in pocket L1 Sensor pocket for DN15/20 (HMAC/POCKET4MM) L1 = 4 mm, D1 = G 1 / 2 B D1 Sensor pocket for DN25/40 (HMAC/POCKET50MM) L1 = 50 mm, D1 = G 1 / 2 B screw 1. Mount pocket in pipe. 2. Insert probe as far as bottom of pocket and tighten screw.. Fill pocket with thermally conductive oil. 4. Seal pocket. Heat Meters TG20116 Issue 4, 28/05/201

The Trend TWP converters may also be connected by a straight 9 Way D socket to 9 Way D plug cable. The meter connection is polarity independent. Use standard 2-wire telephone cable to wire the bus. Note that the cabling for an system requires no specified cable routing or network (e.g. star, series, etc.) d Or EMIC/MBA The EMIC/MBA can connect to a maximum of between 8 and 2 meters depending on its version. The adjacent diagram shows the physical connections. The Supervisor, IQ controller, EINC, and EMIC are connected to the Ethernet bus. The EMIC is connected to its meters using the BUS). The HMM meter takes the measurements and these are read by the EMIC using BUS protocol. The EMIC stores this data in memory and calculates further measurements. Trend system devices can then read the measurements from the EMIC using Trend network communications. The EMIC is a member of the internetwork, and its firmware simulates a Lan with each meter represented as a virtual outstation (e.g. a virtual IQ Controller). A supervisor (e.g 96) can connect to the EMIC by way of a vcnc (virtual Comunications Node Controller) in an EINC (or xtend/einc L, or IQ). In the above diagram, the Supervisor connects to the EINC s Lan using a supervisor mode vcnc. The INCs, Internetwork Node Controllers (EINC s, EMIC s, and IQ s) construct an internetwork. The supervisor can communicate across the internetwork to obtain the meter readings from a vos (virtual outstation). A vos can send Sensor High and Low alarms to the supervisor either through the EINC s vcnc in supervisor mode if the supervisor is permanently connected or through a EINC vcnc set to alarm mode if the supervisor is not permanently connected. The IQ controller is able to send Inter-Contoller Communications to the EMIC (e.g. to obtain meter readings). The IC Comms cannot be attribute comms so are limited to simple Data To and Data From comms. Heat Meters TG20116 Issue 4, 28/05/201 5
