6.3 SETTING THE SWITCHING POINTS AND SWITCH-BACK POINTS /
HYSTERESES
 Press appropriate key
 Switching point/switch-back point/hysteresis number is displayed e.g. "S.P. 1"
 After 2 seconds the current setting ashes.
 Using the "+" and "–" keys, alter the setting.
 After 3 seconds the display switches back.

Notes:
 If "LOC" appears in the display when trying to alter the settings, programming
is disabled. Corrective action: set hardware and software programming
enable to "ON". (See Point 9 "Programming enable")
 If the "+" or "–" key is held down during alteration, the value automatically
advances in larger increments.
 If a setting has been altered, "PROG" appears briey in the display when the
display switches over. The new setting is then saved in the unit.
5. Digital display
After switching on the supply voltage, the unit briey displays "ETS" and then
displays the current temperature.
Notes:
 In the basic settings the display can be altered so that, once switched on,
the unit displays a switching point or the maximum value permanently. In
this case "S.P. 1", "S.P. 2", "S.P. 3", "S.P. 4", or "MAX" appears briey on the
display following the switch-on message. The current temperature can be
displayed briey by pressing the "+" or "–" key.
 If the current temperature exceeds the nominal temperature of the unit, it can
no longer be displayed and the display begins to ash.
 If the current temperature is below 0.5 °C, then 0 is displayed.
6. Output function
6.1 RELAY OUTPUTS
The ETS 1700 has 4 relay outputs. One switching point and one switch-back
point and/or one hysteresis can be set for each relay. The appropriate relay
pulls in when the pre-set switching point is reached and drops back when the
temperature falls below the switch-back point.
Whether the unit operates with adjustable hystereses or adjustable switch-back
points is determined via the "switch-back mode", in the basic settings (see Point 8).
Switch-back mode is set to "hysteresis":
The pre-set hysteresis determines the switch-back point (switch-back point =
switching point minus hysteresis).
Switch-back mode is set to "switch-back point":
The switch-back point is set directly.
Abbreviations: "S.P.1" .. "S.P.4" = switching points 1..4
"HYS.1" .. "HYS.4" = hystereses 1..4
"r.S.P.1" .. "r.S.P.4" = switch-back points 1..4
6.2 ANALOGUE OUTPUT
Analogue output signal 4..20 mA or 0..10 V
(adjustable in the "Basic setting" menu)
