Temp control =yes) and steam ( Steam error

0 no steam in this bath
The available steam codes are combinations of three
yes/no
decisions, as described below. These
decisions are summarized in Table 5: Summary of E-P Plus Steam Code Choices, page 32 .
• Early defines when steaming should begin. Answer Yes to start steaming at the lowest safe
level. Answer
No
if steaming should only begin after the commanded level is achieved. Usu-
ally, a “Start Steaming Early” code (4, 5, or 6) is used when the machine receives only cold
water or when the hot water in the plant has a relatively low temperature. Use a
No response
if the machine has both hot and cold water valves and the commanded temperature is lower
than the hot water temperature.
• After defines whether steam is allowed in this bath after temperature has been achieved once
and subsequently fallen below the commanded temperature. A No response prevents a second
steaming after temperature is first achieved. Use No if chemicals or goods may be damaged
by steam after a chemical injection (as in bleach baths). Answer
Yes
if temperature should be
maintained for the full duration of the bath step and goods or chemistry will not be adversely
affected by the introduction of steam into the cylinder.
• Timer defines whether the timer runs or stops while steaming up to temperature. Stops causes
the timer to stop counting until the commanded temperature is first achieved.
Runs
is for use
when some temperature fluctuations are acceptable or when it is certain that the commanded
temperature will be nearly achieved while filling. Use
Stops if temperature must be achieved
before adding chemicals, otherwise software will suppress this chemical-add choice.
1 Early=No; After=Yes; Timer=Runs. Control does not start steam-
ing until commanded liquor level is achieved; if necessary, steam
is allowed after temperature is first achieved; timer runs while
steaming up to temperature.
2 Early=No; After=No; Timer=Stops. Control does not start steam-
ing until commanded liquor level is achieved; steam is not al-
lowed after temperature is first achieved; timer stops while
steaming up to temperature.
3 Early=No; After=Yes; Timer=Stops. Control does not start steam-
ing until commanded liquor level is achieved; if necessary, steam
is allowed after temperature is first achieved; timer stops while
steaming up to temperature.
4 Early=Yes; After=Yes; Timer=Runs. Control starts steaming at
lowest safe level; if necessary, steam is allowed after temperature
is first achieved; timer runs while steaming up to temperature.
