Mechanical Installation

Note: The power supply is intended for installation within the enclosure of another product.

The power supply modules can be m ounted to a standard DIN rail or be directly mounted to a panel using screws. Hardware facilitating both mounting methods is included as an integral part of the case design.

On the back of each module are molded DIN r ail guide fingers. The design allows the module to easily hook onto and s lide along a s tandard DIN rail.

Special clamps are provided on the case that allow you to lock the module in place, once it is in position.

Continuum Power Supply Reference

Page 10

Once the module is in the desired pos ition, it is locked to the rail by pushing the bottom clamps inward. A ft er the bot tom is secure, press the top clamp inward to complete the operat ion.

These clamps, when extended, provide an alternative m ethod of m ounting to the DIN rail. You can mount the module dir ec tly to a panel using the reinforced mounting holes provided on each of the c lam ps .

Building Ground Requi rements

Be sure that all equipment f r om Andover Controls is grounded to true Earth ground. True Earth ground protec ts the equipment from transients and other power surges in the area. We cannot guarantee that the controller system will oper ate as documented without a properly grounded ins tallation.

An example of a sub-standard gr ound is a galv aniz ed s teel cold water pipe. As the pipe corrodes, it does not act as a true gr ound. The corrosion acts as an insulator, raising the potential of the pipe with respect to the ground.

When lightning strik es in the area of the installation, it dr astic ally c hanges the potential of the E arth. Since properly grounded Andover Contr ols units respond to changes in potential more rapidly than poorly grounded electrical systems, a poorly grounded building tries to reach ground through the Andover Controls system. The surge of current can destroy electronic components on the controller board. Surges of much lower potent ial than light ning als o im pac t the reliability of the equipment.

Inspecting the Ground

Be sure to have your grounds inspec ted before you begin the installat ion pr oc es s to be sure your municipality follows the National Electric al Code.

Many municipalities

do not follow the code and often hav e s ubs tandard electrical grounds. Check your ground as follows : Inspect the building power dist r ibution panel for Earth-gr ound termination. If the

ground termination is any of the following, it is not adequate and mus t be cor r ected:

Does not exist.

•

Is connected to a corr oded or galvanized pipe.

•

Is connected using a small gauge wire ( les s than 14 AWG).

•

Be sure your Andover Controls c abinet is connected to the ground with a copper conductor that term inates at the distribution panel.

UPS Connections

The following information pertains to the PS 120/240 AC 50-U model only.

Backup Battery Connection

The PS 120/240 AC 50-U power supply inc ludes pr ov is ions for connecting an external lead-acid battery supply to power the system in the event of a main AC power failure.

An external 24 Volt batt er y pack m ay be sized to provide the hold-up time specif ied by system requirements. Using standard 12V or 24V batteries, (120 to 160 W•Hr), the built-in UPS cir c uitry provides a backup time of 60 minutes @ 35 Watts power consumption. The integr al 15 Watt battery charger has a worst case charging t im e of 48 hours with two (2) 12V, 7.0 AHr batteries.

Output Power Connection

All Continuum power supply modules inc lude a c onnec tor on the right upper side of the case for distribution of the 24 VDC that it generates. Other Cont inuum m odules (CPU, I/O) use this output as their primary power.

The power output connec tor is a five pin male assembly that is designed to easily insert directly into the left side (input) connect or of any CPU or I/O module. The signals within that c onnec tor are as follows:

PIN Function

5 +24 VDC 4 24 VDC Return 3 No Connection 2 Low Battery * 1 AC Power *

* Only on PS 120/240 AC 50-U

The power supply generates a +24 V DC s our c e for all other m odules in the system. This power source is loc ated on pins 4 and 5.

The UPS version of the power supply ( P S 120/240 A C 50- U) inc ludes two power status signals on pins 1 and 2. Their f unc tion is as follows:

AC Power is a logic signal that is intended to communicate to an attached CPU module that AC power is available. When AC is interrupted and the power s upply has switched to UPS batt er y mode, this s ignal pr es ents a logic low to the CPU. The CPU can use this signal to star t an order ly s yst em shutdown. For more information on the use of this signal refer to the Continuum CPU Reference #30-3001-703.

Low Battery is a logic signal t hat is intended to communicate to an attac hed CP U module that the voltage of the battery has dropped below 22 Volts. When t he power supply is in UPS battery mode, this signal presents a logic high to the CPU. Should the battery voltage dr op, this signal switches to a logic low. The CPU us es this s ignal to start an orderly system shutdown. For more information on the use of t his s ignal refer to the Continuum CP U Referenc e #30- 3001- 703.

Continuum Power Supply Reference

There are two ways to connect the power output of the power supply to other

modules in the system:

Direct connection through CPU

•

Auxiliary power connect ion

•

Direct Connection Through CPU

The power supply module can direc tly connect to others without the us e of cables through a system of built-in plugs and jacks. All modules except the power supply include two complementary module inter-connectors.

The power supply becomes the first module feeding the CPU. All other modules are then connected to the CPU.

Creating a system is as simple as physically plugging the modules together into a stack.

I/O

In vertical extended systems, I/O modules may be located above or below other modules. In this case, cable as s em blies br idge the I/O modules together.

Auxiliary Power Connection

In situations wher e a lar ge num ber of I/O modules ar e us ed, t he power av ailable from one supply module may not be suff ic ient. In these scenarios an auxiliary power supply can be connected t o s upply nec es s ar y power t o the extended I/O group.

All Continuum power supply models c an be us ed as aux iliar y power s upplies . However, the UPS version ( P S 120/240 A C 50- U) must be modified slightly before it is used.

Generally the auxiliary power s upply is added to a remotely located group of I/O modules. The I/O modules that are to be powered by the auxiliary supply still c onnec t to the other modules so that data may flow between the functional blocks of the system, however, these I/O modules must receive power from only the auxiliary supply. A special cable elim inating the 24 VDC signals is connected between the last I/O module powered by the main power supply and the remotely located I/O modules powered by the auxiliary supply :
