1.1 Introduction

The Daniel Digital Rate Totalizer (DRT-899), 3-9008-800, is an explosion-proof pulse input

rate/totalizer fully featured for demanding applications in hazardous areas or in the

harshest environmental conditions. It can be programmed using the four through-glass

buttons, without removing the cover, or with four internal push-buttons.

The numeric rate display reads up to five digits and the alphanumeric total/tag display

reads up to 7 digits. The total overflow feature reads up to 12 digits. The alphanumeric

display can also be programmed to display any combination of numbers and letters up to

seven characters long for use as engineering units and/or the process identification tag.

The backlight increases the visibility of the display under various lighting conditions. The

enclosure contains threaded conduit holes and integrated pipe or wall mounting slotted

flanges.

Setting Description

Password menu

options

Three programmable password selections can restrict modification of pro-

grammed settings, prevent resetting the total or grand total without the pass-

word, or permanently lock out the ability to change or reset the grand total or

any grand total related settings, making a non-resettable grand total.

Pass: Restricts modifications of programmed settings without re-entering the

password.

Pass T: Restricts the reset of total without re-entering the password. Disables

the manual mode reset contact.

Pass GT: Restricts the reset of grand total without re-entering the password.

Enables a non-resettable total and permanent lockout of grand-total related

settings with a specific password.
