Micronics 216 manual Connectors, Pulse Cable Connections

For Reflex Mode attach the guide rail (Figure 3) to the pipe as shown below. Turn the locking nut on the fixed transducer anti-clockwise, screwing it down on to the pipe surface. Do not over-tighten , causing the guide rail to lift off the pipe.

Set the separation distance (Figure 3) by sliding the floating transducer along the scale until the front edge of the block is at the recommended distance displayed by the electronics. Now turn the locking nuts on both the floating and the fixed transducers anti-clockwise, until they make finger tight contact with the pipe surface. To mount the transducers in Diagonal Mode, (Figure 4) and the instructions on pages 20-21 of this manual.

Now Press ENTER to read flow. Pressing the appropriate key on the keypad can change flow units. An additional key press will change the timescale of the reading - hr/min/sec.

PARTS AND ACCESSORIES

Connectors

There are four sockets on the electronic housing. Two for the transducer cable assemblies (Blue down/Red up), one for the pulse output, one for the PSU/charger unit and one for the optional 4-20mA output. Please specify 4-20mA output in your order so that it can be configured prior to dispatch.

Pulse Cable Connections

Pulse output – Centre (White) positive, Screen (Silver) negative.

4-20 mA Output connections (optional) only added to software versions 216-3 & 216-2

Charger (Use only the charger supplied.)

The charger is supplied with universal plug-in adaptors. When the instrument is charging, but switched off, the display reads ‘CHARGING’. It also displays a battery and plug symbol. CHRG is displayed next to the word ‘Batt’ when in flow mode and the battery charger is connected. When the battery charger is disconnected the display will show a % battery level in the flow mode.
