Model 840 "Spyglass" Gage

The optional Curtis Model 840 "Spyglass" Gage is designed to provide a cost effective means

of communicating the various system parameters from the Curtis PMC Model 1297 Motor

Controller.

The basic Spyglass display contains an 8-character Alphanumeric LCD display along with 3

LED's (1 red, 1 yellow and 1 green). A 6 LED model is also available. 

The LED's may flash to draw attention to system failures as well as indicate the

safe operation of the system while being either steadily lit or extinguished.

The LCD display provides details of the system operation such as operating

hours, battery charge condition, maintenance reminders and specifics

pertaining to any faults encountered.

The Spyglass Gage is available in a 52 mm round case with a glass face,

a rectangular DIN mounted Gage or uncased for custom installation.

Connection is provided by an 8 pin Molex connector.

The Spyglass Gage is rated to the SAE J1378 standard for Shock and Vibration. It

can withstand temperatures between -10C to 70C when used with the optional freezer

accessory. The encased Gages (round and DIN) are rated to IP65 for the front seal and IP40

for the rear seal.

Backlit display is also available as an option.
