Telemetry power taken from a new 6amp breaker installed on din rail within the pump control panel by A J Speechley.

4” tray-work routed around pump station to carry power and signal cables. Metal marshalling enclosure and tray-work connected to pump station earth system using 6mm earth cable. Upstream water level frame mounted over the drain. The frame had a 2 metre arm to span the drain so extra support was given to the assembly by bracing the existing handrail to the pump station wall.

Level Sensor Installed in stainless steel housing. Brass ODN marker bolted to floor.



Sump level cable routed into pump station sump and coiled, ready for when WIDB expand the Telemetry system in the near future. Weed screen panel drilled (22mm), lamp and warning label fitted.

Door contact installed; contact wired to small junction box. Signal cable routed around pump station, clipped to wall.

Relays, contactors and current transformers installed within pump control panels

Where drilling has taken place within control panels, all drill and cabling debris has been swept and hoovered up.



All power and signal cables have been routed around site and dressed into cabinets.

Quantity Cable Type Description Type

1 2 core SWA Telemetry Power 230VAC

1 12 core braided Weed screen DINS/DOUTS

2 12 core braided Water Pumps DINS

1 12 core braided Grease Pumps/ELL

1 4 core braided Pump Current AINS

1 2 core SWA Upstream Water Level AIN

1 2 core SWA Sump Water Level AIN

Where cables enter/exit building, holes drilled in walls have been sleeved with 20/25mm conduit.

Outstanding Installation Activities

CW Engineering to provide the weed screen signals.

Signal cables to be numbered/ferruled and terminated within control panels

Signal cables to be numbered/ferruled and terminated within marshalling panel

Fit cable idents to all telemetry cables

Fit idents (labels) to pump status relays and CTs

Point up brickwork where antenna and level cables enter building



Beggars Bridge PS01 (1 pump site / weed screen) Midi8 RTU wall mounted. 5db cellular whip antenna extended (5m) outside for better signal quality. Marshalling enclosure wall mounted. Switched fused spur installed (fitted 3Amp fuse)

Telemetry power taken from a spare 6amp breaker from the distribution board mounted within the pump control panel. Circuit breaker marked TELEMETRY.

4” tray-work routed around pump station to carry power and signal cables. Metal marshalling enclosure and tray-work connected to pump station earth system using 6mm earth cable. Upstream water level frame mounted over the drain. The level sensors 2 core SWA cable was routed around the drain within a 20mm galvanised conduit system. Upstream water level cable enters the pump station via the pump sump. We note the poor quality condition of the pump sump cover.

1 12 core braided Water Pump/ELL DINS











Relocate door contact using bespoke bracket to achieve a more positive connection

Clip 12 core braided cable to wall just below pump control panel



Wype Dole PS14 (1 pump site with weed screen) Midi8 RTU wall mounted. 5db whip antenna remains box mounted as standard (no need to extend outside) Marshalling enclosure wall mounted. Switched fused spur installed (fitted 3Amp fuse)

Telemetry power taken from a new 6amp breaker fitted in a spare fuse position within the Wylex distribution board.

Existing SWA cables repositioned on the existing tray-work so these and the new Telemetry cables could be managed more neatly.



Upstream water level frame mounted over the drain. To find a suitable, safe position on a stable undamaged section of hand rail, the framework had to be mounted outside the compound.

Manor Farm PS09 (3 pump site / weed screen / grease pumps) Trial site for Temperature Sensor and Rain Gauge. Midi8 RTU wall mounted. 5db whip antenna remains box mounted as standard (no need to extend outside) Marshalling enclosure wall mounted. Switched fused spur installed (fitted 3Amp fuse)

RTU, marshalling enclosure and spur connected to existing metal trunking using 32mm couplings.



Telemetry power taken from an existing spare breaker (far right)

Rain Gauge installed on hand railings in front of the pump sumps. Signal cable runs within the kee-klamp frame exiting in 20mm flexible steel ring conduit before entering the 20mm fixed galvanised conduit system.

Upstream water level frame bolted to the floor using M10 raw bolts. The frame has been given additional support by strapping it back to the existing hand rail.







HP823 temperature sensor wall mounted outside the pump station. Signal cable enters the building via the air vent. Cable is clipped to the pump station wall before entering the top of the marshalling enclosure via an M20 plastic stuffing gland.




Wired door contact mounted and cabled back to marshalling enclosure, via the small IP rated junction box. Need to manufacture a small bespoke bracket to mount the wireless contact to the metal door frame.


The Hand/Auto switch arrangement differed at to previous sites. Previous sites had a 230AVC supply turned on/off in the Auto switch position. This enabled us to operate the coil of our relay to genrate a volt free contact to mimic the auto position on the Telemetry. With certain “timed”scenarios (a combination of other swicth positions), the 230VAC supply on the auto switch is not available, the switch can be operated but no mains supply is turned on or off.



Lee-Dickens returned to site on Monday 24th April to meet with Matt Cullip of A J Speechley to investigate this matter further. After some time spent trying to understand the pump logic at site, it was decided it would be a cheaper solution to replace the Hand/Auto switches, replicating the current switch operation but providing Lee-Dickens with an auxiliary set of volt free contacts to be used to mimic each pump being IN AUTO or NOT IN AUTO. Where drilling has taken place within control panels, all drill and cabling debris has been swept and hoovered up. All power and signal cables have been routed around site and dressed into cabinets.
