YSTEM ALARMS/TROUBLESHOOTING ______________________________
The Denali M1 has two system alarms that when triggered will
show on the display. When an alarm is displayed the system will
not attempt to heat or cool the coolant.
TANK LOW: Liquid reservoir level is too low. Unless filling for
the first time, check all outside plumbing lines for leaks. Once all
leaks are sealed, remove the cap and add more process fluid until
the alarm disappears.
attempt to repair unit,
as electrical shock
hazards exist inside.
RTD OPEN or RTD SHO RT: The temperature sen sor has failed or
its connector has come loose. Turn off the chiller and disconnect
the AC power cord. Contact SSCS for an RMA number to return
the unit for RTD replacement.
Important: The tank level low alarm will automatically reset when
the tank is filled. The RTD failure alarm will not reset until the
system power is turned off.
OTHER ISSUES:
COOLING CAPACITY INSUFFICIENT: If the chiller is not
providing sufficient cooling, check that the air inlet and outlet are
not restricted and that the fan is running. If airflow is not restricted,
contact SSCS technical support.
RS-232 COMMUNICATION NOT WORKING: If the RS-232
communications does not seem to be working try cycling the power
to reset the communications. If the problem persists, call SSCS
technical support 845-296-1300.

ENALI M1 RS-232 COMMUNICATION ______________________________
The Denali M1 comes with a modified (pin-out) RS232
communication port. The chiller uses this port to communicate a
comprehensive set of control parameters with a Host PC - these
parameters are outlined in Section 7.2. This port is a 9-pin female dsub connector and is found on the front of the chiller
(see Figure 3A).
Note also that pins 1 and 6 on this port are connected to a dry contact
relay and thus the RS-232 connecting cable must be customized.
This relay is "closed" when the unit is functioning properly and the
RTD temperature is within the Alarm Range. The relay is “open”
when the RTD temperature is outside the Alarm Range or any other
fault exists.

2) Read chiller set point
Host sends command byte = C1 (hex)
Chiller sends command byte = C1 (hex)
Chiller sends LOW data byte = set point value in hex (LB)
Chiller sends HIGH data byte = set point value in hex (HB)
3) Read the actual temperature
Host sends command byte = C9
Chiller sends command byte = C9
Chiller sends LOW data byte = actual temp in hex (LB)
Chiller sends HIGH data byte = actual temp in hex (HB)
4) Read the faults table
Host sends command byte = C8
Chiller sends command byte = C8
Chiller sends faults data byte = fault data in hex
Notes
1) The Oasis can store 8 bytes of transmission. It is recommended that the transmissions be limited to
1 data exchange of one, two, or three bytes (depending upon the data being communicated), until
the master has received the acknowledgement from the Oasis.
2) An acknowledgement of the transmission will be sent back to the master when the Oasis reads the
data. In the case of data transmitted to the Oasis Controller only, the acknowledgement will be the
command byte. In the case of data requested by the master, the acknowledgement will be the
command byte plus the data byte(s) requested.
3) For software that requires data types to be specified:
- Format of command bytes: number, “word”, unsigned, MSB first
- Format of sent data bytes: number, “word”, unsigned, LSB first
- Format of received data bytes: variable length string
4) If RS-232 communications does not seem to be functioning, cycle the main power to reset.

POTENTIAL HEALTH EFFECTS ---------------------------------------
Inhalation:
Vapor inhalation is generally not a problem unless heated or misted. Exposure to vapors over an extended
time period has caused throat irritation and headache. May cause nausea, vomiting, dizziness and
drowsiness. Pulmonary edema and central nervous system depression may also develop. When heated or
misted, has produced rapid, involuntary eye movement and coma.
Ingestion:
Initial symptoms in massive dosage parallel alcohol intoxication, progressing to CNS depression,
vomiting, headache, rapid respiratory and heart rate, lowered blood pressure, stupor, collapse, and

unconsciousness with convulsions. Death from respiratory arrest or cardiovascular collapse may follow.
Lethal dose in humans: 100 ml (3-4 ounces).
Skin Contact:
Minor skin irritation and penetration may occur.
Eye Contact:
Splashes may cause irritation, pain, and eye damage.
Chronic Exposure:
Repeated small ex posures by any route can cause severe kidney problems. Brain damage may also occur.
Skin allergy can develop. May damage the developing fetus.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders, eye problems, or impaired liver, kidney, or respiratory function
may be more susceptible to the effects of this substance.
4. FIRST AID MEASURES
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a
physician.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an
unconscious person. Get medical attention.
Skin Contact:
Remove any contaminated clothing. Wash skin with soap and water for at least 15 minutes. Get medical
attention if irritation develops or persists.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids
occasionally. Get medical attention immediately.
Note to Physician:
Give sodium bicarbonate intravenously to treat acidosis. Urinalysis may show low specific gravity,
proteinuria, pyuria, cylindruria, hematuria, calcium oxide, and hippuric acid crystals. Ethanol can be used
in antidotal treatment but monitor blood glucose when administering ethanol because it can cause
hypoglycemia. Consider infusion of a diuretic such as mannitol to help prevent or control brain edema and
hemodialysis to remove ethylene glycol from circulation.
5. FIRE FIGHTING MEASURES
Fire:
Flash point: 111C (232F) CC
Autoignition temperature: 398C (748F)
Flammable limits in air % by volume:
lel: 3.2; uel: 15.3
Slight to moderate fire hazard when exposed to heat or flame.
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Containers may
explode when involved in a fire.
Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. Water or foam may cause frothing. Water spray may be used to
extinguish surrounding fire and cool exposed containers. Water spray will also reduce fume and irritant
gases.

Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing
apparatus with full-face piece operated in the pressure demand or other positive pressure mode. Toxic
gases and vapors may be released if involved in a fire.
6. ACCIDENTAL RELEASE MEASURES
Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective
equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel
from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect
liquid in an appropriate container or absorb with an inert material (e. g., vermiculite, dry sand, earth), and
place in a chemical waste container. Do not use combustible materials, such as sawdust. Do not flush to
sewer! US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of
reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-
8802.
7. HANDLING AND STORAGE
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage.
Separate from acids and oxidizing materials. Containers of this material may be hazardous when empty
since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the
product.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
50 ppm Ceiling
-ACGIH Threshold Limit Value (TLV):
50 ppm Ceiling (vapor)
Ventilation System:
A system of local and/or general ex haus t is recom men ded to keep em pl oyee exposures below the Airborne
Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of
the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the
ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for
details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face respirator with an organic vapor cartridge and particulate
filter (NIOSH type P95 or R95 filter) may be worn for up to ten times the exposure limit or the maximum
use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is
lowest. A full-face piece respirator w ith an organic vapor cartr idge and particulate filter (NIOSH P100 or
R100 filter) may be worn up to 50 times the exposure limit, or the maximum use concentration specified
by the appropriate regulatory agency or respirator supplier, whichever is lowest. Please note that N series
filters are not recommended for thi s material. For emergenci es or instances where t he exposure lev els are
not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air-purifying
respirators do not protect workers in oxygen-deficient atmospheres.
