All ten of the EPS200 programs are stored in nonvolatile RAM and can be downloaded to a host computer. The EPS200 programming command set provides the user optimum flexibility for developing sophisticated chucking algorithms for multiple process conditions.
2. INSTALLATION 2.1. Installation. The EPS200 is designed for installation in a standard 9.5 inch equipment half-rack or it can be use as a desktop instrument. Figure 2.1 - EPS200 Rear Panel 2.2. AC Power Requirements. Power is supplied to the unit via the IEC 320 receptacle, located on the real panel.
2.6. Load Connections. For proper operation and continued reliability, the high voltage outputs of the EPS200 must be electrically isolated from extremely high DC bias voltages, high power RF fields or other sources of potential damage. It is highly recommended that only accessories manufactured, or specifically authorized, by Gripping Power, Inc.
Figure 3.1 - EPS200 Front Panel 3.2. The Front Panel. The EPS200 front panel user interface is simple to operate. The operation of the various switches is explained in the following sections. The four line, backlit LCD panel provides program and status information.
EPS200 via the RS-232 serial port. Refer to Appendix C for RS-232 interface specifications. A versatile command protocol has been developed for the EPS200 with the intent to make it a flexible production or development instrument designed to fit any need. Refer to sections four...
> a [sp] cc [sp] dddd [cr] All messages sent to the EPS200 must start with an ASCII '>' (hex 3E) or the following fields will be ignored. The following one byte code [a] is the unique address of the target unit. This code is a hex-ASCII value ranging from 0-9 and A-F.
Even when the EPS200 is in local mode, the host computer can still poll the unit via RS-232 to determine why the unit is not responding to configuration changes by decoding the status byte (RS command). The host computer can prompt a user to toggle the front panel mode switch to the remote position, so that processing can continue.
4. PROGRAM AND CONTROL COMMANDS 4.1. Introduction. The command set of the EPS200 has been designed to provide the user with outstanding process flexibility. In addition to basic on and off commands, there are a wide range of reporting, configuration, and control commands. All EPS200 commands, except SO, WF and WT can be used in immediate mode, as shown in the examples.

Receive: >0 SI 500 [CR] 4.2.9. (RM) Report maximum voltage. The RM command is used to indicate the maximum full scale range of the EPS200. All units have a 0 to 1000 VDC or 0 to 2500 VDC range. Send: >0 RM [CR]...

>0 -250 [CR] 4.3.5. (MV) Measure volts at terminals. The MV command returns the measured value of the voltage at the EPS200 output terminals. The voltage value is expressed in volts. The sign will be positive (+) or negative (-).
>0 900 [CR] 4.4. T1, T2 and T3 timer commands. The timer commands allow the user to reset, load, start and display the timer data. The EPS200 has three process timers: one general purpose and two high-voltage activity monitors. Timer 1 (T1) is a user programmable timer that can be used as a countdown timer, when used in conjunction with the WT command.

The user must set the bits to the preferred state throughout a program. If an abort (AB) command is received, or a fault is cleared, the EPS200 will automatically reset the bits to the default state of clamp is up set and clamp is down cleared.
The clamp is up output is an open-collector output and will be driven low, to digital common, when the bit is in the on condition. Send: >0 SU [CR] Receive: >0 SU [CR] Gripping Power, Inc EPS200 User s Manual...
In local mode, once a program has been started by pressing the high voltage switch and a WF is encountered, the EPS200 will wait for the switch to be set to the off position. In digital or analog remote mode, once a program has been started by setting the high voltage go on bit and a WF is encountered, the EPS200 will wait for the high voltage go on bit to be reset.
Receive: >0 CP [CR] 5.4.3. (CA) Clears all programs. The CA command clears all ten of the EPS200 stored programs. The user is prompted for a Y(es) or N(o) response to confirm that erasure of all of the stored programs is desired.
> a [sp] nn [sp] cc [sp] dddd [cr] All program instructions sent to the EPS200 must start with an ASCII '>' (hex 3E) or the following fields will be ignored. The following one byte code [a] is the unique address of the target unit.

REMOTE/LOCAL switch. 6.4. No Output. If the EPS200 does not produce a high voltage output, verify that the unit is properly powered and that the LCD display indicates a ready state. If the unit could not achieve voltage compliance, or a overload condition exists, an 'Overload' message will be displayed.

No parity and one stop bit is required. Modem control lines, such as RTS and CTS, are not provided. No handshaking protocol (such as XON and XOFF) is supported. The host system must delay data transmission to avoid overflowing the EPS200 serial buffer. Gripping Power, Inc...

I/O should be referenced to pin 5. An external common connection between pins 5 and 10 will not alter the performance of the EPS200. Pins 1 and 3 are optically isolated from DC power and DC common. A simple remote control interface can be accomplished by connecting pins 3 and 4 together and connecting pin 1 to DC common, via a switch, to set the high voltage go on active via the digital interface.
