M4557 - Model 9210 Nitriding Controller

Electrical Installation

The Model 9210 requires 24VDC, 4 Watt, 60 Hz, single-phase power. A 24 VDC power supply is required and is generally included as part of the Model 9210 system. This power supply has a universal input that can accept between 60 and 265VAC. Power should be applied in accordance with the electrical drawings that have been supplied. Since each installation is unique for each site, the customer is responsible for providing adequate power and making it available to the Model 9210 power supply.

SSi requirement:

MOV’s must be wired across the isolation relay coil terminals on all isolation relays that are connected to solenoids. Further…. MOV’s must be connected across the HOT and NEUTRAL wires when the solenoid is

wired to them. IT IS AN ABSOLUTE MUST to have the MOV’s at BOTH LOCATIONS.

Instrument Start-up

On power-up, the Operator Interface will display a logo screen for thirty seconds and then switch to the default status screen. The logo display can be terminated early by touching the screen.

Flash Card & Flash Card Reader

!Never remove the flash card when the Operator Interface is ON.

To properly shut down the Operator Interface, press the Menu button, and select Shutdown. At the prompt, press Yes to shut down the operator interface. This will bring you to a conventional Microsoft Windows screen. Sliding the black switch (located directly over the green power connector) to the operator interface to the OFF position will turn off the power.

Once the Operator Interface is turned off, remove the compact flash card cover at the top of the display unit, exposing the card. Press the release button and the card will pop out of the slot. To replace the flash card simply return the card to the slot, making sure that the release button is in it’s up position, and replace the flash card cover to it’s proper position. To restore power to the unit, move the black switch to the right or ON position.

Operator Interface Screen Saver

The operator interface has a default screen saver. It automatically blanks the screen after ten (10) minutes of non-activity. To disengage the screen saver, simply touch the screen and it will re-appear.

A typical Nitriding Control system consists of two panels, a Control Enclosure and a Flow Panel.

The variety of input and output combinations available with this system allows SSi to configure the Model 9210-Nitrider to control Nitriding (temperature, % dissociation, and back-pressure) or just to monitor % Dissociation.

The Control Enclosure contains a 24 VDC power supply, SSi’s Model 9210 Controller, flush-mounted operator interface (Advantech touch-screen), an Allen Bradley Micrologix 1200 PLC, a ring-back alarm system with enunciator, terminal blocks, isolation relays, a hi-limit temperature controller and a UPS unit. The Model 9210 has several control outputs, allowing the customer to choose what variables to control, and how to control them. The 9210 is also used as a recipe programmer to control the furnace cycle from startup to cool down. The operator interface allows the operator to interface with the Model 9210 to view/modify Process Loops, Program status and to modify operating parameters as necessary. The operator interface also contains a Flash card that is used as to datalog Furnace parameters and provides the capability to transfer historical data from the Flash card to any PC that has the SDRecorder Utility
