4.4.3 Running the Optional Step Test

Introduction

You can test the recorder’s mechanical operation by running a step test. This test is initiated using the keypad as described in Table 4-21.

This test prints a step pattern, which is independent of any chart settings, with horizontal lines drawn by both pens at each 10 % increment on the chart (see Figure 4-5).

WARNING

SHOCK HAZARD

When the unit is powered a potentially lethal shock hazard exists at the AC line connections at TB1 on each printed circuit assembly (behing the chart plate). Make sure the unit power is disconnected before starting the procedure. More than one switch may be required to de-energize the recorder.

Failure to observe this precaution can result in exposure to a potentially lethal shock hazard.

The test will run for one complete revolution of the chart before it stops itself. The chart revolution for the test takes approximately 2 minutes, regardless of configured chart speed. However, the test can be

terminated at any time by pressing the DISP

key.

Additional automatic self-tests

At power-up the recorder runs self-diagnostics on the printed circuit assembly for each pen. See Section

4.5.1.4and Section 8 – Troubleshooting and Pen Alignment of Recorder with Display for more information about these diagnostic tests.

Procedure

Use the procedure in Table 4-21to run the step test.

		Table 4-21 Procedure for Running the Step Test
Step	Press		Action/Result
1			Make sure the cap is removed from the tip of each pen and the chart is
			installed. (If you plan to store or ship the recorder, save the protective caps
			for the pen tips. Replace them if the recorder is taken out of operation.)
2			Being careful of the shock hazard at TB1, swing out the chart plate and
			set SW5 on the printed circuit assembly on the right (pen 1) to the setup
			position, toward the top of the board.
			Be certain that the Lockout level is "CAL" or "NONE". The self-test will not
			run otherwise.
3			Apply power to the recorder.
4			Until INP 1 indicator is lit on the left side of the operator interface.
