Some more detail:

The standard motive force of the Drive Assembly consists of a PMDC motor driving through an integrally mounted planetary gearbox. This Gear-motor mounts directly to the drive case’s flange mount and the

drive shaft connects to the Drive Cam-shaft via a keyed connection. The Cam-shaft is supported either

end by oversized sealed bearings so as to eliminate all overhung loads. This greatly increases the life of the Gear-motor’s gearbox which can be an issue with other drives.

The Cam-shaft has another sealed over sized bearing acting upon a Cam-follower. The Cam- follower

has a large bearing surface area and is supported by a sliding, self-lubricating bush of Ertalyte. The Cam

-follower is directly connected to the Chemical Injection Pump’s plunger and is driven in the pressure

stroke by the off-set in the Cam-shaft. The connection between the Cam-follower and the Cam-shaft is a rolling one by way of the large roller bearing. The Cam-follower is returned for the suction stroke by an internal spring once the Cam-shaft has rotated past the maximum pressure stroke point.

Because the Drive Case is manufactured from square hollow tube, we are able to mount a Chemical Injection Pump on any and all of the 4 faces. This means one Gear-motor can drive up to 4 pumps per drive case. Because all drive case components are over-designed, it is practical to inter-connect up to 4 drive cases to be driven from the one gear-motor provided the gear-motor has sufficient torque and

power capabilities. It is also possible to mount a second drive gear-motor horizontally opposed to the other, so as to increase the amount of power available. This in turn, allows us to use various voltages and AC current motors both as standard, Hazardous Area or client specials.

 

The standard Timer Module can be mounted directly on the Drive Case or remotely. It is housed in the same square hollow tube material as the drive case. The 12 or 24 VDC module consists of:

l A fuse holder

l An electronic encapsulated timer

l An Off/Timer/Continuous selector switch

l A variable delay controller

l A Power available indicator lamp

l Plug connections for power supply and supply to gear-motor

The Solar Drive can be supplied with or without the standard Timer Module. If the standard Timer

Module is not supplied, the Drive can easily be integrated in to a third party’s control system providing

the correct supply voltage and amps are supplied to the Drive’s gear-motor. Alternatively, we can supply

an iSAT System that also fully integrates with our Drive. The following pages describe how iSAT can be the solution be it a simple single unit control to the very sophisticated monitoring & control of numerous Chemical Injection Pumps remotely with Satellite/Internet override from any PC connected to the world- wide web.

SiA is a systems integrator, so although we offer a component only supply facility, we mainly carry out complete design, build, installation and commission solutions. In other words and End-To-End Solution

Monitoring & Control (iSAT)

SIA designs, manufactures and markets its own and OEM satellite communication modems & systems

for asset tracking, monitoring, and control applications. Our systems enable data messages to be sent

ａnd received from small, low-powered terminals (often solar powered) over satellite and mobile phone

networks. Users receive near real-time notification of asset location, on-board information and alarms via

or via web user interface. The user determines the exact data to be collected and the frequency at

which it is transmitted and received. The same system allows messages to be sent to the remote located

modem and asset. This gives the system a 2-Way Monitoring & Control ability.

The iSAT System in more detail

The iSAT System can best be described as a near-real-time, 2-way, end-to-end wireless communication

system that facilitates complete M2M (Machine to Machine) interfacing and HMI (Human Machine Interfacing)

with all the attributes of a full SCADA system.

Typical Out-going messages from the RTU (Client Application) to iSAT:

Status of the various sensors, monitors and devices connected to the RTU抯 I/O at

any specifically nominated time or event

GPS Position

Date & Time of the message

Date & Time of when the status (record) was taken.

Alarms generated by certain preset but variable conditions sensed by the RTU

Acknowledgements of messages received

Typical In-coming messages from the iSAT to the RTU:

Requests for instant messaging (Polling)

Changes to the Reporting intervals

Changes to Alarm Set Points

Switching Digital Outputs On or Off

Provisioning of new sensors

Over-The Air Programming
