Winco DGC-2020 - Manual (Page 22)

CAUTION
Replacement of the backup battery for the real-time clock should be performed
only by qualified personnel.
Do not short-circuit the battery, reverse battery polarity, or attempt to recharge
the battery. Observe polarity markings on the battery socket while inserting a
new battery. The battery polarity must be correct in order to provide backup for
the real-time clock.
It is recommended that the battery be removed if the DGC-2020 is to be operated
in a salt-fog environment. Salt-fog is known to be conductive and may short-
circuit the battery.
Type Tests
Shock and Vibration:
EN60068-2-6
Dielectric Strength: IEC 255-5
Impulse: EN60664-1
Transients: EN61000-4-4
Static Discharge:
EN61000-4-2
Shock
15 G in 3 perpendicular planes
Vibration
Swept over the following ranges for 12 sweeps in each of three mutually perpendicular planes with each
15-minute sweep consisting of the following:
5 to 29 to 5 Hz:
1.5 G peak for 5 min.
29 to 52 to 29 Hz: 0.036” DA for 2.5 min.
52 to 500 to 52 Hz: 5 G peak for 7.5 min.
Radio Interference
Type tested using a 5 W, hand-held transceiver operating at random frequencies centered around 144
and 440 MHz with the antenna located within 150 mm (6”) of the device in both vertical and horizontal
planes.
HALT (Highly Accelerated Life Testing)
HALT is used by Basler Electric to prove that our products will provide the user with many years of
reliable service. HALT subjects the device to extremes in temperature, shock, and vibration to simulate
years of operation, but in a much shorter period span. HALT allows Basler Electric to evaluate all possible
design elements that will add to the life of this device. As an example of some of the extreme testing
conditions, the DGC-2020 was subjected to temperature tests (tested over a temperature range of
–100
C to +115C), vibration tests (of 5 to 50 G at +20 C), and temperature/vibration tests (tested at 40 G
over a temperature range of –80 C to +90C). Combined temperature and vibration testing at these
extremes proves that the DGC-2020 is expected to provide long-term operation in a rugged environment.
Note that the vibration and temperature extremes listed in this paragraph are specific to HALT and do not
reflect recommended operation levels. These operational ratings are included in Section 1 of this manual.
