Page 17: Relay Wiring
Installation Relay Wiring Refer to Figure 2-5 for the relay contact wiring. The Z-tron IV relay has double-pole, double-throw (DPDT) dry contacts. The relay serves as a switch and does not provide the power to operate an annunciator or other equipment. All relay connections are made to the terminal strip on the electronic unit. -

Page 21: Time Delay Control
Operation Time Delay Control The time delay adjustment is located on top of the instrument, as shown in Figure 3-1. It is used to help stop a repeated relay output due to agitation or waves in the vessel. CAUTION: THIS adjustment is a 270º (¾ turn) potentiometer. Do not turn it beyond its mechanical stops or damage to unit may occur. -
Page 22: Failsafe
Z-tron IV Point Level Control Failsafe Failsafe describes the level condition which causes the output relay to de-energize, and determines the condition of the relay upon loss of power or upon the failure of most components. • The failsafe mode may be selected in the field by changing the position of the right slide switch located on the top of the instrument. - Page 23 Section 4...
