Loss of Control Power and Self-Check Alarm Contact Test
Follow these steps to test the loss of control power and the self-check alarm contact:
1. With control power applied to the DPU1500R, check the self-check alarm contact and the STATUS LED. Normal
status is indicated by a green LED.
2. Interrupt the control power to the DPU1500R. The self-check contacts should return to their normal state.
3. Reapply control power and check the DPU1500R to see that all settings were properly retained.
New Firmware Installation
Introduction
These instructions give guidance for the installation of the modification/upgrade kit part number UP-587X-xxx.
Specific instructions included with any update kit would supersede the instructions given here.
Precautions
To avoid personal shock, use caution when working with energized devices. Only competent technicians familiar
with good safety practices should service the relay.
These instructions do not purport to cover all details or variations in equipment, nor to provide for every
possible contingency to be met in the installation. If particular problems arise which are not covered
sufficiently please contact our Technical Support Group at 800-634-6005, or 610-395-7333, or Fax 610-395-
1055.
Should the downloading process be interrupted before completion, a special recovery procedure may be possible
for units with surface mount construction. Refer to the procedure "Recovery from Download Failure" given below.
Modification Kit
The modification kit consists of a new External Communications Program floppy disk, a Flash Program Interface
(FPI) floppy disk, and two System Application Firmware (SAF) floppy disks (a CPU firmware version for the
through-hole-component circuit-board design; and, a CPU firmware version for the surface-mount-component
circuit-board design). In Step 2 of the modification procedure you must select the proper SAF disk for the particular
unit you are updating. The modification kit will give details on making this identification.
Modification Procedure
1. Establish communications via a computer connected to the front port using your WinECP communications
program.
2.
Record the serial number, catalog number, and existing versions of firmware Installed in the relay by viewing
the Unit Information menu item.
Important: if the existing CPU version is of the form V1.xx or V2.xx, then select the SAF disk labeled V1.xx or
V 2.xx, for "through-hole" designs. If the CPU version is of the form V3.xx, then select the SAF disk labeled
V3.xx, for "surface-mount" designs.
Maintenance and Testing
Before you proceed with the update process, you must
identify the construction of your unit in order to select the
correct floppy disks from the update kit. Details are given
in Step 2 of the procedure.
