OPERATING NOTES

ENVIRONMENTAL RANGE

The operating temperature ranges from a minimum of -50°F (-45°C) to a maximum of 122°F (50°C) for sustained system operation or 140°F (60°C)

absolute maximum. The entire unit can de-ice and be operational in two hours from a temperature of -13°F (-25°C). The thermostatically

controlled heater consumes 10 watts and cycles on at 70°F (21°C) and off at 85°F (29°C), while the window defroster runs continuously and

consumes 2.5 watts.

PAN AND TILT FUNCTIONS

*50 mph wind-speed proﬁle.

**If manual limit stops are set, “Pan Limit” appears on your monitor when a limit stop is reached (except when you are programming or running

a pattern). This does not apply to scan limit stops.

***When the system reaches the upper limit, “Tilt Limit” appears on your monitor (except when you are programming or running a pattern).

If the proportional pan mode is enabled (refer to the

Proportional Pan

in the

Programming

section), the pan and tilt speeds will depend on the

amount of zoom. At telephoto zoom settings, the pan and tilt speeds will be slower for a given amount of joystick deﬂection than at wide zoom

settings. This keeps the image from moving too fast on the monitor when there is a large amount of zoom. This slowing does not happen when

going to a preset but does occur in turbo mode when high zoom is selected. The minimum pan and tilt speeds are 0.1 degree per second at full

zoom.

SCAN SPEED

Scan speed is adjustable from 1 to 40 degrees per second through the programming menu.

PRESET FUNCTIONS

The Esprit

system is capable of going to 64 preset locations, each with a 20-character label. The presets are numbered 1-32 and 35-66. Refer to

the documentation for your control system for programming presets.

If you command the pan and tilt to go to an undeﬁned preset, erratic operation may result.

Presets 33 and 34 are ﬁxed commands, meaning that you cannot program them. Preset 33 is the “ﬂip” command, which will pan the system

180 degrees. Preset 34 is the “pan zero” command, which will pan the system to the factory-determined zero reference point.

RANDOM, FRAME, AND AUTO SCANNING

Select preset 97 (30) to start random scanning. Select preset 98 (31) to activate frame scanning (three seconds of scanning followed by a three-

second pause). Select preset 99 (32) to start auto (continuous) scanning. Scan limit stops are controlled by software. Refer to the

Limit Stops

section to program the scan limit stops.

When the pan and tilt reaches a scan limit stop, it reverses direction. Select preset 96 (29) to stop a scan. Any pan and tilt or lens command also

will stop a scan.

ZONES

A zone is a programmed pan area with set boundaries and identifying label. The Esprit system has a maximum of eight zones, each with a

20-character label. Zones can be programmed to blank video when the camera pans into the zone area. If a zone is blanked, the system displays

the message, VIDEO BLANK. (Refer to

Zone Blank

in the

Programming

section for instructions.)
